Awww! I'm sorry, Earl.

First of all, I am sure your wife was well aware of what was going on. Gas does not stop when we sleep.

It could be some sort of stomach bug. I know several people who have had a stomach bug lately, many of them it was more gas than anything else. Try to keep a bland diet for a few days (foods that are easy to digest) and maybe take some Tums. Those really helped DD19 as she was going through something (don't know what yet).
I hope you feel better soon!
