I agree with everyone that you should tell your pdoc and follow his advisement about going off your meds. I also wanted to say that I think it is very normal for a woman who is trying to get pregnant to think about sex more. Before I got pregnant I had been taking an antidepressent, a sleep aid, and birth control. I went off all of them and I was also feeling better than too. I had started working out three times a week and feeling good. So alot of it could just be the excitement of the possiblity of becoming pregnant. But just to be safe its best to let your pdoc know what your feelings are so he can be watching you for any signs of danger.
