BuSpar is a mild anti-anxiety medication. I was on it before, and did well on it. Some people find that it does nothing at all for them; it doesn't have a good reputation in the medical field. Pedigogue gave a line here on this forum, that was pretty funny once, but, I can't remember it.
It's not Welbutrin, though, which is an anti-depressant. Totally different.
Good luck on the study, Don. Thanks for sharing with us. And thanks for being part of something bigger than yourself, that could help so many.
Shalom!
