Where is my drive!!!!?

i was on lemotrigine an organic version of a certain antidepressant and i was on them for two months and noticed my drive completely dropped, now i stop taking them because of this side effect and some others but now i have been off of them for a week and my drive is still a little low. how long until im back to normal which would be "horny around my boyfriend every second" mode like i was before, i have also been taking a enhancement pill for a week and hasn't really worked yet so what should i do?
