They are small candy with chocolate centre. Thank you for the info
What is a "chocolate eclair sweet"--a little piece of candy that tastes like a chocolate eclair, or do you mean full-sized chocolate eclairs?
The big ones, of course, will send your blood sugar through the roof!
In either case, though, it sounds as though you have not had a chance for your stomach to empty before you lie down, and the undigested stomach contents are simply leaking back up your esophagus.
There is a kind of "valve" at the base of the esophagus that is supposed to minimize this, but in quite a few people, it does not work well. In general, people with this problem are advised NOT to eat anything for several hours before going to bed.
