paxil and prozac are the worst as far as sexual dysfunction...lexapro and wellbutrin are the best. wellbutrin isn't an ssri like paxil though...so i would talk to your doc, wean off of the paxil while at the same time wean on to the lexapro...if lexapro isn't covered, go to celexa. workin' in a pharmacy, i've heard lots of complaints about paxil, prozac, zoloft, and some about effexor, but none so far about lexapro.
also...just as a side note for anyone taking an ssri...since a lot of guys have trouble sleeping while taking some of the "supplements" talked about on this board i thought i'd mention it. stay away from trazodone as a sleep aid while on an ssri, it can actually cause just the oposite effect and give you a woody that won't go away...literally, to the point of severe pain and permanent damage...just a heads up.
