Add another check in the "horrible" column. I was on the stuff for a little less than 2 months and gained 45+ lbs. I was ravenously hungry all day and all night long, and I started "sleep eating." I gained 30 lbs in the first 30 days, something I didn't think possible outside of "Supersize Me." It took almost a year but I lost it all, but I wish I'd never gone on it to begin with.
