Sigmund Freud's cocaine problem

Editor's note: Nearly 130 years ago, cocaine was the world’s newest wonder drug - touted as a cure for everything from morphine addiction to tuberculosis. And its biggest supporter was Sigmund Freud. Dr. Sanjay Gupta has the fascinating history and what it means for us today on "Sanjay Gupta M.D." at 7:30 a.m. ET Saturday and Sunday.

Whenever Big Pharma unfurls its latest “blockbuster” drug, I am carried back to the era when the biggest wonder drug on the market was cocaine. Yes, cocaine!

In the early 1880s, pharmaceutical houses touted it as a cure for everything from morphine addiction and depression to dyspepsia and fatigue. It was widely available in tonics, powders, wines and soft drinks before its mass consumption created a cadre of raging addicts demanding medical attention.

Tri Challenge: My brain is my last obstacle

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.

I’m in the homestretch right now. I’ve put in all the hard work over the last several months and I’m ready to reap the rewards.

Up until about a month ago, I was enthusiastic, excited, and jumping to go but, lately, I’ve been kind of hesitant. I can’t really describe it with accuracy. I still very much love triathlon, my coach is awesome, along with all the wonderful people who’ve helped me out or trained with me along the way, but I can’t help but feeling a little depressed.

Why am I not faster by now? I don’t look like your "typical triathlete." How come I’m not this or that? All of these self-sabotage questions are flying through my head at 100 mph and it’s all I can do to get on my bike or throw on my running shoes because I’ve only got two and a half weeks left. I’m not going to get magically faster in that amount of time. No one else cares how fast I can run or what I look like in my race kit except for me.

What the Yuck: Can I catch bedbugs?

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: A guy I just started dating has bedbugs. Can I catch them from him?

Indirectly, yes. Bedbugs, or Cimex lectularius, are not passed person to person - they are only attached to humans for 5 to 10 minutes while they feed on blood (yuck, I know).

How much vitamin D do I need?

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

Question asked by Terry of Dodge City, Kansas

I have some 2,000 IU vitamin D capsules that I am about to take. I'm a 60-year-old male, in pretty good health and not overweight or underweight. I'm also active. I've read that 2,000 is the upper limit for daily dosage, and I don't think I need to take that much anyway. The capsules I have cannot be split, so could I use them every other day and be OK? Thank you very much, and have a great week. I appreciate your site and the info.

'Darth Vader's' mom: We focus on today

Editor's note: There’s something you might not know about the star of the year’s biggest television ad from the Super Bowl. Max is only 6 years old and he’s already had eight surgeries for his heart condition. This weekend, he gives Dr. Sanjay Gupta an inside look into his life and explains what he’s doing to help other sick kids. Watch "Sanjay Gupta M.D." at 7:30 a.m. Saturday and Sunday.

In this post,  Jennifer Page shares what being Max's mom has taught her. 

“Kiss your baby. He has to go to the NICU. We have found structural damage to his heart,” said the neonatologist. In a split second, life changed forever.

As they pulled him from my arms I sobbed, “I love you, Max,” over and over. My tears covered his sweet face. A new mom with a baby I couldn’t hold, a baby I couldn’t protect.
