I was taking 300mg in the am and 300mg in the pm for about 6 months now. At first it seemed to work but then I didnt take it as regularly and then I was just recently put on 300mg in the am and 600mg at night and I've noticed I've been very angry and easily flustered and getting mad at the smallest things. I can't tell if I'm just stressed out or what? I also smoke weed and I'm trying to quit so that might be it to. Can someone help me please?
