Hello Hashi/bipolar mom: I'm sorry you are having such a difficult time. Yes, one of the things I always think about, with regard to going on med's, is the potential weight gain. I'm not on any med's at the present time & weight gain is one reason I plan not to go back on... that plus the cost. I'm retired. I have health insurance. But the out-of-pocket cost is still significant & the med's never did me that much good.
I do not have a therapist. I've tried a few but they never amounted to anything. I still technically still have a pdoc. But at my last appointment a couple of weeks ago, I told him I wouldn't be coming back on a regular basis. I'll just go in once a year in order to keep my foot in the door, so to speak. Coincidentally, he also suggested Neurontin to me at a recent appointment. I mentioned to him that I have been experiencing some tremor-like feelings throughout my body & he said Neurontin would take that away. But, as I recall, Neurontin has been prescribed in the past for seizures. And I think it can do a number on one's teeth & gums. (Perhaps I'm mistaken.) But just the possibility that this could be a problem was enough to prevent me from even considering it.
Anyway, I don't have any particular suggestions to offer you. I just thought I would let you know I read your post & I have some sense of some of the concerns you raised. I wish you well...
