Eh (don't hate anybody), various APs are prescribed for *anything* these days. Anxiety, to "augment" AD, insomnia, many other things. So it means a little.

You went off it not so long ago. It can be "illness coming back" or it can be prolonged withdrawal. That thing is usually worse and longer then average doctor is willing to admit (maybe because most of them never went through it?). In your place I would try to wait it out a bit longer if you can do it. Depends on level of suck you can tolerate.

Ultramar made effing excellent points. Depends on what is worth it for you... only you can decide.
