Fecal. And like you I used to have A LOT of gas all day. It made me so depressed and uncomfortable. I did a parasite cleanse called "13 parasite Cleanse 13" and it was a 10 day parasite cleanse. Google search 'healthyself360'and find the website link from that and you can find out more about the cleanse and the owner.If you have anymore questions or just need someone to talk to feel free to PM me anytime.
