choked on my acid reflux

Okay guys, I think it's time I start taking some tums. I have been having terrible acid reflux since I've been maybe 17 or 18 weeks (I'm 21+6 right now) and I have just been trying to curb it with milk and avoiding spicy foods. But last night I ate Mexican food, went to sleep, rolled over on my back in the middle of the night, and woke up choking not being able to breathe from me choking on my acid reflux! I sprang up, was able to cough a lot of it out, the hard coughing led to me now throwing up, and this morning my throat and chest still burns. I've not been wanting to take any meds cause taking medications while pregnant kind of freaks me out, but last night scared the shit out of me
