I usually wake up sick to my stomach

I don’t eat or drink before bed. However, upon awakening, I feel nauseous and exhausted. Half the time I vomit. Nothing but stomach acid. It can be quite painful. Can’t eat or drink until about an hour after I’ve been up. I’ll just throw it up otherwise. I got drunk last night. I fell asleep on it. When I woke up, in the morning, 5 hours later I felt refreshed. I wasn’t nauseous. In fact, I actually woke up hungry. I woke up feeling pretty good. I should probably drink more often
