If you've already been diagnosed with BP, then ignore my post. But I wouldn't jump to conclusions about what your doc said. It's true, of course, that Seroquel isn't just used for sleep, but he may have just been saying that because it's true, not because you're taking it for BP. I take a small dose for sleep (and a bunch of other meds for BP), but the dose I take, per my pdoc, is not therapeutic (doesn't help with BP), it's only 25mg and the therapeutic dose is much higher (I don't know how much you're taking).

In any case, I think your best bet is to ask your doc (preferably a pdoc) directly what your diagnosis is, rather than base it on this comment you mention. Just suggesting you be careful here.

I wish you the best, whatever your diagnosis, and I hope you keep posting and find whatever treatment works best for you.
