Drinking alcohol with any form of Gambling is always a bad mix, why do you think
casinos in Vegas give booze away for free when you are at a
roulette table or slot machine. it loosens the purse strings and you just get deeper and deeper in debt to the gambling.
I was at a Casino when a drunk walked in and asked if he could play at our table and the entire table yelled "yes please do!" We didn't mind who's money we would be taking.
It is so easy to fleece a drunk when they are giving money away, and they do it constantly. Some time it is so easy it gets embarrassing, at our local pub, we had a drunk stranger ask what the buy-in was to a cash game we were playing and I said whatever you want, it is a cash game and we usually buy-in for £10-£20.
£50 was his first buy-in and it took us 30 minutes to take that from him, when he asked for another £50 I asked him if he thought that was a good idea, as we were regular players who know how each other plays, and all he said was "yes but you don't know how I play" 20 minutes later he was broke again.
When the fun Stops, STOP! (he should have done)
