bipolar disorde
"My only two complaints about lithium are the potentially detrimental effects on the kidneys and the nausea. I first started taking lithium in college but stopped because of excessive nausea and vomiting. Five years later, I'm trying it again because the other mood stabilizers I have tried were not too helpful (abilify "numbed" me, zyprexa turned me into an angry bear, seroquel made me sleep all the time, depakote gave me bad tremors, etc). 
I do have to adjust my lifestyle habits though while on lithium...more water, less sodium or acidity in foods, take it nightly...but vomiting/intense nausea and renal problems down the road..."
