I didn't know if I should tag this on the thread on drugs and OCD behaviour, but I'm intrigued by the connections.

My neuro on first diagnosis told me that statistically most PWP are non-risk takers, with low emotion swings.
Personally, I own up to mildish (and occasionally excessive) OCD behaviour patterns over most of my life - Gambling, smoking, drinking etc
I wondered if those whose experienced compulsions such as gambling shopping binges or hyper-sexuality on taking the drugs, previously had lower mostly controllable patterns, or did it come as a total character change ?
