I never was on Lithium, I am on Lamictal.
I sure hope all these side effects subside soon. Sometimes with meds, well with me, it took a few times to get the right dosage for me with the Lamictal, Klonapin, Trazadone. Plus finding the right anti-depressant, which is Cymbalta and that works good for me.
Hang in there, meds take time to get into your system and adjusted.
Good Luck,,,,,Nikko
