Lithium Carbonate and hand tremors

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've been taking Lithium (800 mg) for about 15 yrs.after experiencing severe post partum depression. I've experienced the common side effects like headaches, nausea, muscular weakness, however I've been lucky not to have hand tremors.
My issue is with my memory and with recalling words. Lately I've been having a hard time expressing myself and it's really frustrating and embarrassing! I feel stupid. I'm also bi-lingual so it's worse.
I've also been taking Xanax (.05 mg/day) for the past 5 yrs, for panic attacks that started after I started taking Lithium. I only get these panic attacks in my sleep. So I'm wondering if panic attacks are a side effects of Lithium?

i'm 17and have been on lithium for 5 months. i've gained 12 lbs, have frequent headaches and hand tremors, at least the mania is gone.
