Lithium
"I have depressive bipolar 2 which never is a huge issue until there's less Sun due to it combining with my seasonal mood disorder to send me over the edge. I started taking lithium in January and I recently have just stopped (July) so about 7 solid months or so. Granted this worked great I felt more clear headed the first couple months except it messed my stomach up horrible in combination with my irritable bowel syndrome. Plus my periods turned brown and would be two weeks late every time which is horrible nerve wrecking. My hormones completely lost it and still have  yet to go back to normal. Granted I'm only 18 and I could be growing once more and I've changed my acne routines but my acne completely changed making my skin."
