R-CPD (Retrograde Cricopharyngeus Dysfunction) is a condition that makes it impossible to burp for people who suffer from it. This is because of a muscle in the throat never learned to relax properly. It affects more people than you'd think and causes a lot of discomfort, extreme bloating and social anxiety. The most common medical treatment is a botox injection, but it's expensive and not accessible to everyone.
There even is an entire r/noburp subreddit dedicated to people who suffer from R-CPD.
I am a Software Engineer from Germany and have suffered from R-CPD all my life before finally curing myself last year.
I wanted to make the self-teaching process easier for everyone who comes after me, so I built Learn2Burp. It walks you through the actual exercises with video guidance, builds a workout plan around your specific situation, and includes a burp tracker. There's also a wiki covering the questions I wish I'd had answers to when I started.
Basically everything you'll ever need to teach yourself how to burp!
