I have GERD and an ulcer, and burp a lot. I burp when I eat and also when I drink water. I have been on Prevacid for about 15 days. I havn't had any heartburn or pain anywhere. I watch my diet very carefully. VERY! I do wonder about all the burping. Eveb after a night's sleep, I wake up and burp. Help Please, as I am so curious about this.
