INCREASED GAMBLING, SEXUAL OR OTHER INTENSE URGES.
Ok, I have Restless Leg Syndrome. Had no idea what it was for years; as a kid, I was told it was "growing pains" but that explanation didn't make as much sense once I was in my 30s. One day I asked a doctor and he said, Restless Leg Syndrome. It's not something I would ever consider treating with drugs.
