Lithium Carbonate and meds

Hi, I'm rapid cycling bipolar. I was taking 300mg of lithium a day and it helped a lot. Then started the crying and paranoid feelings again. I also took venlafaxine 150mg. My psych doc increased the venlafaxine to 225mg time released and the lithium to 300mg twice a day. I have really bad headache that make me sick to my stomach. Bad hand tremors, weight gain, extreme thirst, dry mouth, constant urination, confusion, memory loss, bad concentration, heart palpitation that are very scary and problems with my balance. I've been taking these meds for a year now. I'm hoping that I just need to get used to the new dosage. On the plus side mentally I'm great, it's just the physical aliments that are getting me. I have an appt. with my doc on the 13th. I'm hoping that he'll have some answers for me. Hang in there I know how you all feel! please tell me if anyone else has these same symptoms. Thanks,

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.
