How can you focus if you're drunk? It's not a good condition to trade. I never tried it before but I know I can't do it because I tend to fall asleep if i'm drunk already. But I think it depends on each person's alcohol tolerance because there are people who seem not drunk and can still focus well even they consumed too much.

Anyway, it's not advisable to trade when you're under influence of alcohol. Even we're not drunk, we do lose and sometimes committing mistakes so what more if you can't focus?
