Initially I thought it might have something to do with sugar free drinks but by now I believe that's less likely. It happens much stronger when I drink caffeine, often caffeinated sugar drinks. So I assume it has something to do with this. But it also happens when I don't take any caffeine, it's just less strong.
I have not yet done a proper medical examination since that is very annoying to do. Other than the burping I have zero issues.
I feel strongly that it has something to do with what I eat and I am trying to figure that out. But caffeine is hard to stay away from...
Lately I've got a feeling that there might be a psychological component to it as well. Around that time I quit my job, tried my hands on a few personal projects, got a light depression and so on.
This article is very interesting since I spend most of the day in front of a screen, mostly reading, bad posture, very hectic etc. Caffeine always makes me tense and could very well be a catalyst.
Any suggestions for how I could monitor my breathing?
