I have had to slowly recall why I felt what and when and what I ate that day. Alcohol is an occasional thing. I can't have caffeine. Actually there is only one kind of soda pop I can have that won't give me heartburn. Cantaloupe is out, as are uncooked onions unless they are red onions.
Poppy seeds are a no no.
I haven't figured out why they don't always give me problems. I exercise by walking my dog. Sometimes we can go a little farther than others. And then there are those days, it's down to the corner and back. That is as far as I am going to make it.
