"lithium was hard for me to take at first. if i did not eat enough with the medicine i would vomit. the medicine works for me but i do not like the fact that i have gained weight and it causes acne. i have done everything i can to have clear skin but it does not matter what i do. lithium is cheap and effective but like i said i don&#039;t like the side effects. i am going to try tegretol when i go back to the doctor."
