I’ve been taking Lithium for about five years. It didn’t always stabilise my moods but has kept me alive by making me much less impulsive. My only side effects have been mild hand tremors and a mild thyroid issue that was resolved by thyroxine. I’m glad you started it as it can be a game changer for many people. If not for you there are many other safe options to stabilise you. For me Lithium took two months to take effect. I think it was when I got my blood levels right. Hang in there and make sure you drink lots of water and get your kidneys and thyroid checked every few months.
