as rainyday suggested, i took my wellbutrin in the morning. i wasnt on cymbalta though. wellbutrin is known to jack people up. it didnt do that for me. i always have had problems with insomnia or so i thought. what it turned out was i had a HIGH sensitivity to anything energy inducing. so i had to cut out anything caffienated. no energy drinks. no tea. and those vitamin waters, the b vitamins in there also keep me up at night so i cant drink them either. so see about paying attention to that and limiting energy inducing foods (sugar even) in the afternoon and see if that helps.
