Sometimes it is pure luck. Spoke to someone who's antidepressant helped her with depression, anxiety and sleep. I've never come across a med that helped me with everything. If I did, of course I would not take more than one. But now I happen to need one for each of those three issues. I have been in monotherapy for the longest of time, and I had some stupid pride about it. Like I'd be "better" for it. Duh! Of course it's not good taking more than you need, but I happen to need what I'm on. It's not a contest.
