@specified, i know how ur feeling. The worst is trying to cope with the deficits of antipsychotics and watching whats left of ur life still wither away in jeopardy. In my experience welbutrin helped my medication induced sexual dysfunction but only to the point that i could get it up and stuff, it didnt make sex super pleasurable. In our situation its best to approach it from a lot of angles. If i was literally u id stop the meth, then id get prescribed cialis or viagra, and also take L-Arginine (helps with nitric oxide and getting hard and also feelig horny- something about invega blocks nitric oxide release which is needed for engaging in sexual activities/blood flow and shit i think), zinc, and maybe L-tyrosine. The l-tyrosine and l-arginine will give u a dopamine rush that will be a little like a stimulant. Also if ur not prone to psychosis smoke some weed before having sex, it can help temporarily reverse the blockage of dopamine receptors from the invega long enough for u to have a window to be horny and actually achieve a rewarding orgasm. For example if i want to have a pleasurable orgasm i work out and shower, take l-arganine (1000mg) zinc and L-tyrosine (750mg) together. Then i also smoke a hit or two of weed and then go look at porn. Finally 10-11 months off of this poison and im able to have an orgasm that i look forward to- but keep in mind i have to take all those things leading up to it. Ignore me if this is tmi but it sucks so i thought id share what works. How long since ur last shot again?
