Tri Challenge: Checking things off my list

Since January, six iReporters have been training in the Fit Nation Triathlon Challenge. We’re following along as they prepare to compete alongside Dr. Sanjay Gupta in the August 7 Nautica NYC Triathlon.

Lose weight and get fit – check

Set a better example for my patients and their parents – check

Lead a healthier and more active lifestyle – check

Get off my medications – check!

That’s right I am off my medications! My application for the CNN Fit Nation Tri-Challenge was triggered by a visit to my primary care provider for the first time in many years. I left that appointment with three medications, two for blood pressure and one for lipids. Within a couple months I was off of one of the blood pressure medications after losing some weight and having some lightheadedness. I am happy to report that my doctor has now taken me off all of my medications.

Tri Challenge: Strength in numbers

Since January, six iReporters have been training in the Fit Nation Triathlon Challenge. We’re following along as they prepare to compete alongside Dr. Sanjay Gupta in the August 7 Nautica NYC Triathlon.

Well that's it. I've completed my last long workout before the big race and I must say it was the best weekend of training I've ever had. It all came together like never before: swim, bike and run.

My coach Eric called me during the week to tell me this would be my last big workout before the race. I was excited to step up to the challenge but a little nervous as well. I knew how important it would be to make a statement, not to anyone else, just to the guy who use to live in my body. If I had any self doubt I planned on crushing it this weekend.

What the Yuck: Am I narcissistic?

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.

Q: I keep hearing how everyone these days is narcissistic. How do I know if I am?

The fact that you are asking probably means you don't have narcissistic personality disorder, because people who do have it generally don't have enough self-awareness to question their own behavior.

Weight loss 'sleeve' a good option?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

Question asked by Lynn C. of Madison, Ohio

I have had a weight problem for 23 years. I have lost and regained over 400 pounds. My weight-loss doctor is offering the "sleeve." I have been told because of my gastroesophageal reflux disease that the Lap Band is not an option, nor is the more well-known gastric bypass because of a high family history of cancer.

I have all the problems common in morbidly obese people, some I had even when thin. High, difficult-to-control blood sugar, blood pressure and a mild heart issue controlled by meds. The sleeve has been done only a few years - can it be a good option for me?

Tri Challenge: Tapering before the race

Tri Challenge: Tapering before the race

Dr. Tom Hackett is an orthopedic surgeon at The Steadman Clinic in Vail, Colorado. He also serves as the head team physician to the U.S. Snowboard Team, assistant team physician to the Colorado Rockies and medical adviser to the Major League Baseball Alumni Association.

The word taper refers to a gradual narrowing or thinning of an object and has direct implications to race day preparation. Several scientific studies and years of experience with athletes from all walks of life have shown that a well-thought-out and executed tapering program can improve performance on the big day.

Essentially it means giving your body rest but at the same time maintaining your fitness level. You need to be fully recovered from your training so you can give it 100 percent through the finish of a race and let all that hard work leading up to the big day payoff.

Tylenol maker sets new, lower doses

The manufacturer of Tylenol announced new, lower dosing instructions for the painkiller on Thursday in an effort to reduce accidental overdose from acetaminophen, the product's active ingredient.

McNeil Consumer Healthcare, a division of Johnson & Johnson, is recommending the maximum dosage for extra strength Tylenol be lowered to six pills - or a total of 3,000 milligrams (mg) a day, down from eight pills or 4,000 mg which is the current maximum daily dose.

Dr. Drew on 'Octomom': Going beyond the caricature

Editor's note: Dr. Drew Pinsky, a board-certified internist, regularly interviews people in the spotlight to learn more about their emotional lives. Nadya Suleman will be Dr. Drew’s guest on a special edition of "Dr. Drew" on HLN Thursday at 9 p.m. ET.

Nadya Suleman - we gawked, we gasped, we rolled our eyes. Ultimately, we turned her into a cartoon character, giving her the moniker "Octomom" - not altogether unreasonable, considering her bizarre behavior:

To us, it looked like the reckless decision of a madwoman - giving birth to eight children on top of the six she already had. Raising just one child is a world of responsibility - raising multiples, even more so (I know from experience – I have triplets), but 14?

We asked, how could she dive headlong into such a huge commitment, alone.

Diana Nyad: Sharks need our help

Editor's Note: Recent news reports have raised the issue of sharks and how Diana Nyad and her team will react if sharks come near as she attempts to swim from Cuba to Key West, Florida. CNN , following Nyad's preparations for over a year, asked her about her shark plan and how she intended to deal with predators she might encounter in her oceanic journey. Here is Nyad's response:

Sharks have made news in recent weeks, from attacks near U.S. beaches to how they were treated by the team of a fellow ocean swimmer. There were some reports - denied by those involved - that sharks were harmed when Penny Palfrey swam in the Caymans.

I just want to be crystal clear about how my team will handle sharks on our upcoming attempt to make history in swimming the 103 miles from Cuba to Florida: No shark will be harmed at any time during our event.

Sharks worldwide are in crisis.

Tens of millions of them are killed each year just for their fins, often in a disturbing, cruel manner. At this rate, we will lose our ocean sharks within the next decade.

Agreed, our team has worked hard toward this world record. But it is of paramount importance to us that we achieve the dream in perfect harmony with all the creatures of the sea we encounter . In some regard, I am humbly asking the sharks of this particular ocean to allow me to skim across the surface of their home for about three days. I am duly respectful of them, their habits and their habitat, as is every individual on the Xtreme Dream Team.

Is casual sex worth it?

Is casual sex worth it?

Ian Kerner, a sexuality counselor and New York Times best-selling author, blogs about sex on Thursdays on The Chart. Read more from him at his website, GoodInBed.

To do it, or not to do it: That is the question of casual sex - at least as depicted on film.

In both "Friends With Benefits" (currently playing) and the previously released "No Strings Attached," casual sex is anything but casual. It’s carefully weighed, hotly debated, methodically scrutinized and, of course, comically miscalculated. As in most romantic comedies, the casual sex turns out to be quite committed and just a part of falling in love and living happily ever after.

In the movies, blind lust and romantic love often intersect seamlessly, but in reality, casual sex is often an emotional dead-end rather than an on-ramp to relationship bliss.

Anthropologist Helen Fisher describes love as a three-phase system:

1) Lust, in which we can attach to anyone.

2) Attraction, in which lust finds its focus and blossoms into romantic love.

3) Attachment, in which romantic love matures into a long-term relationship.
