This is just a breif article, im accually going to ask my docter for 5mg oxycotin 2X daily along with my lamictal which im going to reduce to 100mg daily.
Im pretty sure lamictal has anti depressent effects are because it lightly brushes the opiate receptors in the brain. I mean think about it, lamictal lowering glutamate which is an exitatory nuerotransmitter will only stop mania not depression.
I dont know if my pyschiatryst will give me the oxycodone because of its taboo for abuse. Yet most docters will whip out presc. for lithium and powerful anti-psychotics with a horsel-load of side effects, yet wont consider a promising treatment.
