"lithium has cut my suicidal thinking drastically and helped my sleep. for 20 years i have fantasized about suicide from between 25 times and 300 times a week consistently. i took latuda and lamictal for bipolar and had very little sleep on both and the suicidal thinking got too intense. been on lithium for 3 months now and the suicidal thinking has diminished to between 0 and 5 times a week. huge difference. have not noticed any adverse side effects. i am on a regular sleep schedule now as well. highly recommended for the overly suicidal thinker like me."
