Stuff like Thermorexein, Ripped Fuel, Xenadrene....
My doctor said they were antagonists and not to take them while I'm on anti-depressants but Dr.'s will say anything to keep you off that stuff!
I used to pop Hydroxycuts with my Paxil. No problems. However, I did start getting bloody noses fairly often. Was it the Hydroxycut and Paxil??? I have no idea. Could be I just wasn't drinking enough water and getting dried out.
