@cheyne sounds like I might be experiencing the same thing. I woke up one morning with gas trapped in my stomach so bad felt like I was going to explode from there I started regurgitating everything I tried to eat even water and my stomach won't tolerate pretty much any kind of food. All I'm able to eat is bananas eggs and toast and this has been going on for almost a year. My stomach bubbles with explosive gas all day long. I just started the antibiotics about 5 days ago but haven't had any relief yet how long did it take before you felt netter
