When I was 18-23, I was just a pot head. I enjoyed drugs, as long as I got to choose which drugs I was taking.
I'm sort of hard headed that way. But, I've made peace with the fact that nobody is trying to hurt me by offering me medicine to treat my specific condition.
Today, I believe that the medicine I am taking is a Godsend if it can keep me from going off the rails. I also know myself well enough to know that exercise, meditation and clean eating are wonderful, but are just not quite enough.
I try not to think in terms of good and evil. It is what it is.
