"ssri&#039;s meant no orgasms and didn&#039;t help me sleep. no such problems with mirtazapine. sex is even better, sleep is wonderful and i get enough and can function within minutes of getting out of bed.  i get brain zaps at sudden noises if i&#039;m relaxed, and it increases my appetite a lot.  thankfully i&#039;ve taken up distance running at the same time. you must exercise on this medicine to overcome the weight gain, which is it&#039;s worst side effect. all up this medicine has been wonderful and after horrible experiences with ssri&#039;s i&#039;m glad to be on it.  found out afterwards that my girlfriend is also on it for insomnia."
