I've been finding myself taking really deep breaths and yawning quite often, especially when I'm just relaxing. It's weird because it doesnt bother me at all during sleep. Ive gone through all the tests and everything checks out fine. My family doctor mentioned it might be stress or overthinking, but Im not really convinced. I can't help but keep thinking about these long breaths. I also deal with acidity issues. Could these things be related? Any advice on what's going on would be really helpful.
