Well I guess I'll see tonight what happens. I had no problems with the Humacleanse caps at lunch. It was really strange this morning since I've never had anything like that. Would die-off show like that just in a 20-25 minute timeframe after taking the caps? To be a little more clear it was a burn from my stomach to my throat. Since I don't normally have heartburn I'm not sure if that's what bad heartburn is like or what. Anyway I'll be taking the 2nd set of Humaworm in a bit here so I'll see what happens tonight.
