Nice! I like what you did with the place :)
I have panic disorder and MVP. To me, having this tracker is priceless. It actually will help me on my focusing techniques to reduce the amount of palpitations I experience.
Others can easily spot the effect of medications. All in all, I think it does much more good than not having it.

From what I know about web sites and ads, it's very much like the the physical world and real estate. Location, location, location. Ads typically appear high up on the page because people notice them there, so advertisers are happy It's really a small price to pay for a free site IMO.
I think MedHelp makes money from the ads. Most Internet sites that are free to users are ad-supported, but some sites also offer a premium service where members pay a monthly fee and they don't see any ads.
If there are enough people who want a premium service, MedHelp might consider adding it.

How did you lose the 45 pounds and how long did it take?
