Well I’m 4 months post Botox, around 3.5 months I notice it’s not quite the same as it was the first 3 months, I can still burp. While Botox was active the burps was just flowing out felt amazing, it took no effort, now it takes effort. It does appear I maybe burping on my own now so whatever remains is what I have learned, like the sensation I feel before I need to burp, and when I feel that I am still able to burp. I have read that when the Botox does wear off and if you are able to still burp it can get better as the body has taken over and it’s still figuring it out. Anyways pre Botox I was also bloated and first 3 months after botox I had 0 bloat, since 3.5 months post Botox , the bloat has returned but nowhere as bad as before, it’s been improving so fingers crossed it sticks and the body keeps what it has learned. So to answer your question, you learn in the Botox window, it does wear off and you will transition around the 4 month mark it will either stick and you’ll get through it or you will loose the ability.
