A good thing for me is that I am very happy when I drink and I also don't lose self-control. That's why this form of entertainment hasn't damaged me.
As long as you're doing both responsibly, it's all fun.
I do not encourage gambling and drinking, this are two major or deadly something that easily leads to gambling addiction, anyone who must gamble should stay clear or away from drinking.
Things to face:
It would make you to lose control
It would make you fund your account excessively even when you do not want it.
It would consume your time in order to secure at least single winning.
Everything is individual. I really do not promote and advise anyone to do such a thing, I'm simply sharing what I find enjoyable and funny. 1.5 litres of beer is not much, it doesn't make you very drunk, especially when you drink it slowly over 2 hours and especially when you already have some level of tolerance built towards alcohol (I often drink once a week with friends).
Btw there was a red round cycle with the number 1 on my profile, it was part of the rewards. I was clicking on rewards and wasn't seeing anything. Today I discovered that it's a daily $CASINO points that I can claim every 24 hours.
