Here is an interesting post from "JohnTall". I am posting it here so that more people will see it.

"Nearly two years ago I posted a note detailing my experience with Taranabant. In that post I fudged my actual weights for concern that Merck might be able to identify me and end my participation in the trial. Since then Merck has pulled the plug on Taranabant and I am no longer concerned about them knowing that I am posting.

My actual experience was that I started at 244 pounds and I lost to 183 in 101/2 months (61 pounds lost). I then slowly regained 9 pounds to 192 and that was my weight when I left the study in December of 2007. I was in the study for 27 months." Read the entire article | Email this article
