Thanks to the several veterans who answered (are still answering) my belching question. As a newcomer I've read many threads in this forum and have not yet seen the following symptom:Occasionally, about an hour after eating, my body seems to lose most of its energy. I have a tremendous desire to simply lie down. I don't feel sleepy or really uncomfortable in any way. I just seem to go limp. This state of affairs lasts for maybe 20 minutes.Bizarre, but true.
