I'm on 2 different extended release anti-seizure mood stabilizers, an atypical antipsychotic for sleep, thyroid hormones (hypo), multivitamin, melatonin, and when needed muscle relaxer (I use it sparingly and only when my pain level is tremendous. Opiates don't work on me. Nothing, not even morphine cuts my severe neck pain from degenerated disks, but small dose muscle relaxer helps.). I also use botanicals daily that help as well with PTSD and mildly with depression and anxiety, legal stuff and no, it's not pot. The plants in me, not everyone, took away my need for the nightmare medicine, which I only found out about within the last year. I also exercise like mad.
Even with all this, my mood is only mostly stable 5 of 7 days, but it's much moreso when I workout more.
