Personal choice IMHO. To each his own. As long as your decision doesn't directly impact or effect someone else's safety or rights, then everyone else with an opinion can go fly a kite.
But..... keep in mind that if your decision places someone else in a position of having to perform a rescue..... then that still counts as impacting someone else's safety.
Personally.... I go on vacation to dive, sleep, relax, read , and......party. I'm a big boy and have no problem diving with a bit of a hangover. Also, I really enjoy having an ice cold brewski.. waiting for me in the truck right after an afternoon dive.... and even if I'm gonna dive again in an hour, it's no big deal. One of the great things about shore diving in Bonaire. No rules, no standards and especially..... no self appointed righteous know-it-alls who think they are experts and that others are supposed to live by their rules.
Took 29 posts for someone to tell the truth! I will admit I have back rolled off a boat with a hangover bad enough I didn't know my name!
