Poll: How does alcohol/smoking affect your thinking?

I never really was into drinking/smoking. But two days ago I smoked full cigarillo and drunk 1/2 glass of white wine at my backyard staring at clear sky in the late evening.

After getting back to my laptop I've found I could concentrate on particular task which is not that complicated, but definitely require quite a lot of concentration (migrate data between old and new app's db with quite different schemas and logic)

I was able to sit at it for a few hours and really did quite a big chunk of work successfully. All of it being a bit tipsy (since I really never drink, even small doses of alcohol/smoke affect me quite a lot)

I am wondering, what is other developers experience is regarding alcohol and smoking?
