54 year old male. I seem to burp and can burp on demand but not sure if it's psychological or not? I try not to think about it and when I'm busy I won't burp at all but other times when I'm driving or just sitting alone I will burp. I also will have some reflux of liquid come back up throughout the day and evening. Not sure what to do. I will also wake up just about every night and and have some reflux. Please advise.
