Lithium Carbonate and doctors

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!

My joints all over my body are painful. I don not know if it is a side effect of lithium because I take other medications. The drugs include femara, niravam, cymbalta, famvir, calcium 1000 mg., a multivitamin capsule, glucousimine, echinacea. please give me some advise as to why I get veryt painful joints and the back of my neck pops constantly throughout the day.
