I'm in a somewhat similar position. New to bipolar, and my pdoc is thinking about lowering my Wellbutrin or taking me off it altogether. I had my second appointment with her and she's leaving me on it for now. Personally, in my past experience, SSRI's seemed to never do anything but bad things for me, and Wellbutrin was the first and only prescription drug (that was prescribed to me at least) I've ever thought did me any good. She thinks tentatively I could be okay if I stay on the mood stabilizer with it, but I guess only time will tell...

I'd suggest forcing yourself to sleep if you still can. Seeing as it's 4 AM, I'm clearly playing with the same fire you are so my advice is unfortunately a little hypocritical, but in my past it seems like when I start giving into the desire to not sleep is when I start going up. It's a really tough call for me right now. I don't know what type of bipolar I have yet, so there's a slight fear if I give into the hypomanic, I could get to full-fledged mania, but at the same time, the rush is so hard not to give into.

I think I'll take a sleeping pill here shortly and try to force sleep.

Best of luck to you. I hope you find the right combination.
