On long dives I take a hydration pack with a bite valve. When your air gets to the point, (excuse me gas) where you feel like you are chewing it, I just take a good pull. Be careful though and practice in the shallows it can be weird taking your reg out sucking water through a hose, swallowing and then clearing/breathing. Have even been buddy drinkin on a dive. Haven't decided on a 5 or 7' hose for that feat yet.
Try and avoid dairy products the night before a dive cuz for most people it is a mucous stimulator.
