When ur cheeks start hurting and the salivating starts . Terrible.

Sounds like alcoholism problems?

When the saliva starts to have that metallic taste.

I REBUKE !

Yup. Absolutely the WORST feeling. I've been throwing up for 3 days. It had been so long since I had last thrown up that I didn't even know what was going on. And then the bitter spit came. You know, that bitter spit that comes right before the vomit. Super fun, had to accept it real quick.
