My husband has waken up in the middle of night with sudden urge to vomit about 3 times in that 2 months. He feels fine otherwise and is in good health. We don't eat too late before bed. I was thinking acid reflux? He does eat a lot of pizza, wings, a lot of acidy foods, and also drinks A lot of soda. About 4-5 cans a day! Any suggestions on what it could be? And yes stop the soda! LoL
