Seems to me you drink out of habit and to refocus/think of how to approach stops when plays are in the other end. If this is the case I recommend getting a cheap mouthguard for the sole purpose of chewing on it. If it is water you need though and you want a massive amount of water check this out.

Not the same one I have but mine is old and military grade. Works, seems the mouthpiece is better angled on this one so might get it and try to see if it’ll fit under my mask.

This one is the one I use. Been great. Use it for walking, at the gym when working out, hiking. Super great on the back of a net. Just snatch up the hose. If you get it and use it this way leave the lid off and keep it unlocked when on the back of the net so you can just grab it.
