I have that too, and I think it's worms. When I've been on the Master Cleanse, oh my god, they go insane. I actually think I have a freakin' moster in my stomach. So I've been parasite cleansing for a long time now. I'm still infected, and I think until I go on the OJ fast and parasite cleanse at the same time I won't be rid of them. It sucks. Raw diet will help too I hope.
