Lithium toxicity
New psych put me on lithium, 300 mg three times daily.
I started getting symptoms I didn't recognize. They were troublesome. Then worrisome. Then I lost touch with myself.
I'd surely like to hear from anyone who has had a similar experience

It had too many side effects for me as well. I also hated having to get my blood tested to check my levels. Some of the older medicines work just fine. I'm on an older antipsychotic now, but it's a good fit for me. I've been on most of the newer drugs and some lasted a while, but it would inevitably have to be changed sooner or later. But I don't know your condition, so I can't say whether lithium is right for you or not. Your problems and mine could be vastly different. I hope you're going to get better soon. The main thing to do is follow your doctor's advice and ask plenty of questions. Be patient enough to give the drugs some time to work. It can be weeks until you start getting noticeably better.

Those reviews report it as everything from a miracle drug to a potential killer. Some had similar experiences to yours.
I have not been prescribed lithium as part of my depression treatment but I did have serious reactions to most all anti-depressants my shrink tried, and much later discovered the dosages were too high for my system. Even at 75, my chemistry reacts to many drugs much like a child's system would, so I need lower dosages.
I hope you can relay your issues to your doctor and it may be you are also sensitive, or perhaps you're having a drug or supplement interaction from something else you take.
Best of luck to you.....
