To be honest my biggest issue that caused the slip was vomiting.
If you find yourself vomiting or things getting stuck and you need to make yourself vomit that is a RED FLAG that something needs to change. Either your eating habits or your fill something would need to be fixed.
Talking to my doctor as well, he said a food to completely stay away from that has caused many slips for patients (and probably helped lead to mine) is popcorn. I was really sad because I do enjoy popcorn, but for me I've had to add to the "forbidden" list along with rice.
