What a question to ask for your very first post lol.
Ive known of guys who like to be medicated while they handicap , they think it clears their mind and allows them to zone-in on crunching numbers .... but as far as going to the casino under the influence or being medicated while placeing bets , i would think is a bad idea.
...but i guess it just depends on the individual. I know a functioning alcoholic and he's not worth a crap when he is sober , and he's not worth a crap after his 10th drink , but somewhere between drink 3 and drink 6 he's sharp as a tac.
