Glasses of water are much more environmentally friendly, (and cheaper) and I think they’re more satisfying to chug since you don’t have the flow restriction at the lid.
I tried doing this once. The bottled I had at the time had a pop cap thing, where you don’t unscrew it. You just lift it up.
The issue came from that I had a bottle of clear face spore cleaner. It also had the same type of lid. This shit was full of deep cleaning chemicals, and what I’m assuming is ethanol. It was in the same area where I kept my water. So, in my still half asleep state. I reached for what I assumed was water. Popped the lid, placed the hole in my mouth, and gave a big suck. Next thing I know. I’m fully awake. My mouth is burning. And there’s a taste extremely similar to petrol in my mouth. And then I realised my mistake.
