I'm also taking Zyprexa and Paxil. Zyprexa made me gain enormous amount of weight. Paxil (or both... I'm not too sure) has plummeted my sex drive. So far so great because I haven't had to go to the hospital in a while so that's a plus. With Paxil, as any other anti-depressant, it takes a while to kick in.
