I had been taking Lithium for 3 years 450mg twice a day. I stopped during my pregnancy, then 2 months after my sons birth I was put back on starting at 450mg twice daily. After about 7 months I was then raised to 900mg twice daily. I found this odd being as I am only 5' 110lbs. I was having digestive problems (diarrhea), dizzy spells, black outs, kidney and liver problems. Among a few other things. I was told that I can file a lawsuit against the company who makes it. Does anyone know if this is true.
