"i went to my doctor with main concern being sex drive. he suggested i&#039;m probably very stressed. and i was, i have two small children. welbutrin helped my sex drive, i quit stress smoking, and it suppressed my appetite. i just felt really unstable, and was lashing out. i took it for a couple of months then asked to change. i was given viibryd. i was given 10mg the first week, 20 the second week, 40 the third. everything was great until i started taking the 40mg. i took it for two days. during those two days i started having panic attacks that i had never experienced before. i thought i was losing my mind! i went back down to 20mg and things got back to normal and i love it! i did experience diarrhea for a while, i&#039;m not sure if it was related."
