hey, so I've started having nausea like over a week ago and at first I thought it was kind of because of stress, but then 2 days ago vomiting started as well in the morning until like early afternoon, same 2 days ago and yesterday and I thought it could have been a food poisoning, but today it was still the case - again in the morning, early afternoon, and I'm no longer sure as food poisoning (in my case at least) lasts usually a day only. now, literally writing this, I can't sleep cause of nausea, although I've not vomited since the morning. any idea what I can do and what could it be?
