Lol, I wish. As far as I know, this isn’t a well documented thing, my PCP was kinda like, “huh, that’s interesting, I wonder how many people are dehydrated because of that.”

The only reason I discovered this is cuz my girlfriend knows me very very well and she suspected there was something off. So she asked me probing questions until we discovered I’m literally drinking incorrectly.

So the best I can do is give you a couple of different ways to drink and see if you notice any difference in how easy or difficult it is to comfortably drink without ingesting air.

So first thing we did was have me drink from a bottle. Any bottle where you can form a full seal around the opening with your mouth. Tilt back and let the fluid fill your mouth as much as possible before starting to swallow. That should mean a very minimal amount of air in the first gulp, and no additional air in each subsequent gulp because it’s sealed.

Contrast that with drinking from a normal glass, and you may find that you’re gulping down air as you’re drinking with each gulp. In that case, a straw will probably prevent you from doing that.

But really drinking from a bottle really illustrated the mechanical difference to me and made me realize my hatred for drinking was definitely born of a physical discomfort which was ultimately from a poor technique.

And after I thought about it, I was like ya know, no one really ever taught us how to drink did they? We all just figure it out, and assume we all learned the same lessons.

This might have all been the biggest factor in me never really being into drinking alcohol, because the very concept always sounded like a chore to me.

Anyway, I hope that helps!
