I'm 32 years old. I've recently been diagnosed with bipolar disorder and am currently taking 1200mg lithium, I was on Prozac and ability before but it caused mania and was switched to lithium. I find that I'm very angry and the smallest things set me off, I told my doc and she doesn't want to change it just yet Bc my levels are good. My questions is. Does anyone else feel mad all the time being on this drug?
