I Have Had This Happen On Several Occasions. I Was

I have had this happen on several occasions. I was eating a bite of steak and it felt like I didn't swallow it completely. After my next sip of my drink, I vomited. It produced a lot of liquid, but very little solids. This started about 21:00 hours on Thursday. Since then everything I try to drink or eat comes right back up. I am not having any trouble breathing and it feels lower. ( Just below the sternum) Any thoughts?
