I know exactly how you feel Joyce. It's common from my experience to have extreme gas during die off. Gas can be caused by many things though so it's not a given. I'm getting ready to go through another parasite cleanse and one of the things that I know to look out for is extreme gas. Check your stool in the morning after. There is likely to be some evidence of parasite or mucous placoid in your stool if it is in fact die off.
I feel like I'm gearing up for a fight for my next round of die off. Bring it!
