Probably 2-3 times a week, I ll wake up at night and have a timely (3 seconds) belch. I might do that 3-4 times in a few minutes and then fall back to sleep. In an hour or so, I ll repeat the same ritual, this might go on 3-4 times during the night. No taste, no pain or burning, just a long belch. It does not seem to coincide with any certain types of food. I m 63 years old and this has been going on for about a year. Sometimes I ll flatulate as well and again no real odor. I do eat a few cookies and drink a half glass of watered down white wine as I read a bit before turning the light out. But I ve been doing that for years and this problem is fairly new.
