Thanks for the reply.
Yes, I do know it is an anti-depressant. I am on it for sleep though, as I have a hard time sleeping through the RSD pain.
I actually slept well with it last night... and I figured out why I hadn't been sleeping well when I increased the dose- I had taken my B Complex at night!

(that does keep some people awake at night)...
I haven't had the problems of being too sleepy and groggy with it, thankfully. Though I am just taking 50mg at night now, and I may be increasing it further.
Thanks again!
