I dont find it surprising that a lot of performers have addictions.. get off work late, always around a party... & they are always invited..
If we were in the situation, and had a driver, almost all the time.. we got to ask ourselves what we would be doing.. Never being at home, is not always comfortable. Hard to say how we would end up, but I think some of us would do akay, and a few would seriously %^%$ up...
