really sick

So I've been sick for a week now and I'm starting to get worried. I plan on going to the doctor this week but I have never been sick like this. It started at migranes, hot flashes and a little nausea. Then it escalated to me puking for 3 days straight. I can't keep any food or water down. Don't worry I did check to see if i was pregnant and I'm not. At work apparently a few people have been off with a stomach virus like mine. Any advice on how to feel better while I wait to go to the doctor. I'm miserable 😞
