Hi,
I've been on Lithium for years and it keeps me stable, I have never had toxic levels even though I have had a few stomach bugs in my time on Lithium.
It has kept me stable and not suicidal, I have not been suicidal in about a year since I was put on it a second time.
It boosts the effect of your anti depressant and its very safe if you take it as specified.
