Yeah that's one of the things they know even among APs which are all pretty similar if you complain about some effect from one of them they'll have a pretty good alternative that won't have that particular effect not to say it won't do something else bad because to some extent they all do but it at least won't do what turned you away from the first...also I was only ever on one med at a time albeit we considered a sleeping pill at times...I know bipolar/sza is harder to manage though and often needs multiple meds...
