Lithium Carbonate and tremors

I have been on Lithium Carbonate (1800 mg/day) for over 4 years. Lived with diarrhea, acne, tremors, etc. throughout, but otherwise loved the drug. After filling toilet with blood several times last week, I went into the hospital. Colonoscopy & endoscoopy revealed severe diverticulosis and severe Barrett's esophagus, respectively. All involved are shaking their heads, as these tests were relatively normal 3 years ago. I suspect Lithium.

I take lithium, 1350mg/day, for 5 years now, and about 2 years ago I started getting tremors but worse in my left hand, so it was actually painful and for a while the doctor thought it was carpal tunnel but it turned out not to be and he didnt know what caused it-now ever since then my left hand has gotten worse & typing with it is a little problematic, its like the nerves are messed up in that hand, it won't always hit the right numbers. Its starting to freak me out a little, but in the last year I've started having episodes where my entire left side goes tingly like its asleep, my vision blurs, I get shaky all over and have such rapid heart palpitations it feels like my entire body is in shock. This lasts for about half an hour usually, has landed me in the ER twice, & they claimed each time not to know what caused it and looked at me like I was making it up, and didn't give me anything for it. I also get the typical symptoms- mild hair loss, memory loss, speech impairment, weight gain (I was 120 now I'm 160- luckily it distributed so its not too obvious), & it does not stop depressive episodes, just shortens them, and I still get anger episodes fairly often, usually as a split second reaction to something very small. I'm definitely looking into getting off of this as it is worrying me, more about the episodes and my left arm/hand issues than anything else, especially that now I have trouble with coordination in my left hand,which sucks because my desk jobs always involve a LOT of typing.

I am taking lithium with a 800mg dosage of sodium valporate for my bipolar.But i cant sleep most nights cause i wake up every hour to wee and my throat is so dry.so thirsty.I also have acne which from my teens i never had any.i also have terrible headaches.I seriously feel like stoping as i dont even see a differences in my condition.

I have been on lithium for almost two years now....Although the does needs increasing here and there. When this happens i get the splitting headache nasuea and tremors. sometimes it is frightening but it seems to go away after a few days. Weight gain? well i've been chubby my whole life, it is a trade off. I am very glade too have been diagnosed and finally am getting stable.
