"i have bi polar was diagnosed last year and since i was a baby i had epilepsy. anyway, i&#039;ve been on lithium for a long time and  hate it. it killed my thyroid. when i started taking it, first blood test i took a month later. when results came out my doctor said i have hypothyroidism now. i had a lot of pain that i could not even move, and i was cold from my hypothyroidism. it was all from this pill. i want to be off of it. i fund anticonvulsant pills that also does bipolar, i showed it to him. and he says that my neurologist has to agree. i see her end of this month. do not take lithium.... it kills your thyroid!"
