gina,
I am so sorry you are going through this. I have been there and understand.

I don't know your relationship with your pdoc, but from what you say I recommend talking to them as soon as possible. If you need a change in meds it often takes a few weeks (as you know) to become effective. So the sooner the better. Get in there and squawk until you get some help. You shouldn't be going through the cycle you are.
