Drunk and want to gamble that's not good, better get rest and when your head clears up you can go for the gamble.
Because I don't think both will go well together.

Its the wrong combination when you are drunk and want to gamble because anyways in gambling chances of winning are less then the house. And on top if you are drunk and cannot control your emotions on losses you may go big in order to recover and might end on a big loss and without you realizing during that time. Later on it would be too late when you realize your mistake.
