Burped and a cloud of medicine came out and major heart burn

So I’ve had heart burn before on this medication but never to this extent or had this other matter occur. I took this on a relatively empty stomach with a few sips of water a few minutes later I burped and a cloud of medicine came out followed by a horrible bitter taste and then awful heart burn and very displeased stomach. I took tums and drank water but it’s still so bad. has anyone ever had this happen?? how long does gross feeling last? and do you have any remedies for it?

omg. lmao. i thought i was the only one that this would ever have happened to.
i was horrified it hurt me so much. i was guzzling water like no bodies business because it hurt so much.
lasted about an hour for me.
