I know ups and down down way the hell downs and over again and doctors call that bipolar, cool. It helps them decide what medication to try first. It is a lot of guess work. If I went to another and he said, no, it is actually something call Beridjieot, I'd say fine, can I take the same drugs?
Notice the overlap in meds? That's what gets me. You can take atypical antipsychotics for moods, psychosis and I hear some for anxiety and insomnia. You can take lithium for unipolar depression, ritalin for attention and sometimes depression, prozac for all that ails you.. It goes on and on and on, so much over lap. Sure, some is off label but, it gets to a point where if it works, it works.
There are labels, that help guide you and then there are psych meds that you eat.
