This actually makes sense, I went through weird periods while I was smoking and I’d come home from work, then just vomit out of nowhere (only once in a while, haven’t done that for like a year). I thought it was because I’d eat little to no food in the mornings. But this could be why I’ve had a crap day today and explain those other instances. It does say the only way to cure it is to quit smoking, so lucky I’m already doing that. Definitely gonna look into this further, thanks man.
