I have been reading much about DCS lately. I'm a new diver and I do want to do it as safely as possible. Not wanting to make light of this type of injury, but if I'm on vacation some place lets say Playa del Carmen in Mexico, although it is better not to drink alcohol before a dive. If a person were to have one drink before they dove though I probably wouldn't, but from what I've read so far is that it would be safer to drink a marguarita then a beer just to the fact that beer is far more carbinated then a marguarita is.
From what I've read over the last few months about DCS its the gas in a person system that has to be bled off in a safe manner, so therefore it is even safer to drink a Marguarita then soda. So why is it that when I've been on a boat dive some of the operators offer soda as a refreshment instead of just water, gater aid or just juice?
