I doubt that there are many people ,on this forum for example, and in general, whose main income is by playing live poker. I am microstakes player and my opinion is not that valid maybe, but i always looked at live scene like smh you do when you want to take a break and relax from serious online grind and hours spent in front of computer screen. Main purpose of live poker is to have fun, and visit foreign countries by playin live, part of that freedom that ol grinders mention. So, i have read that some guys use coke, and all kind of mixtures playin ol. and for me that is perfectly fine, they can lick frogs, eat mushrooms, do whatever they want and no one can pervent that. It looks like this thread somehow is tryin to push poker in someway towards sport like some Olyimpic discipline, which poker is certanly not and is never gonna be.
edit: Also one thing that makes me puke is when i see that ol poker players make smknd list odf"healthy doings" that corelates with ol poker. For example:
1. gonna drink banana shake early in the morning
2. grind for 2 hours
3. lift weights
5. walk a dog
