I have never had my digestive system checked out. I'm kind of scared to. I actually tried going to someone to get colon hydrotherapy done but the damn office is never open!
I do sometimes get a bad taste in my mouth, but my breath doesn't stink for the most part. Funny that you mention that about lying on one side and getting nauseaous. Sometimes when I sleep on my right side in a certain position I wake up sweating. It's like I can almost instantly feel it. I can roll over and it stops. This has been happening on and off for about 10 years.
