Lithium Carbonate and prozac

I am up at this moment, because my stomach is hurting from the lithium. I've been on it now for about a year, but my stomach just started hurting at night after about an hour after taking it for about three months now. Is anyone else experiencing this? I read one post above about it, but that's all. There is no vomiting, but just upset stomach. It keeps me awake. I'm on lithium and lamictal, and Topomax. If you experience this, is anyone taking anything for the nausea? Thank you! And everyone hang in there! You're in my prayers! Don't give up!

I was given Lithium for my bipolar disorder, I was not on it long, maybe about a week before them side effects hit me, it made me sooo weak that I could not even lift my head up, I will be eating and take about 3 chews and would be extremely exhausted, I found out that extreme muscle weakness was one of the severe side effects so I stop taking it and now I am on Prozac
