Someone help me, today I have been feeling really nauseous and have vomited over 7 times in 4 hours, I can t get any sleep, and I think I found the reason why. I have noticed that I m producing A LOT of saliva, watery saliva, although there s nothing of food in my stomach. While I sleep, my body keeps producing saliva and I swallow it involuntarily, making my stomach full up of saliva, making me want to wake up and puke, someone help me, I m 13 only, my saliva is watery as water.
