We seem to have very similar symptoms! Though I have not started Humaworm yet, I think I triggered some kind of reaction when I did my pineapple/pepita flush over 3 weeks ago. I have had SEVERE diarrhea and still have some days of vomitting. I vomitted earlier this evening at the pool/sauna. I'm incredibly weak as a result. It's as if I have food poisoning. Lots of stomach gurgling as you describe. It's just awful.
I've searched Curezone for some kind of relief. I just started to treat my Leaky Gut (I think I noticed you had also been treating Candida as I had been--I had been previously taking anti-fungals). I just started taking L-Glutamine powder yesterday and it is soothing to the stomach--I'm taking it 3x per day. I'm also taking a Calcium Citrate capsule with each meal (it supposedly causes constipation). Also trying to eat more nuts. These are suggestions I found on Curezone.
All along I've also been drinking Bentonite to help absorb whatever toxins and pull these watery stools together. I can only imagine the situation would be worse. I was unable to board a plane due to the severity of my diarrhea last week! My life is pretty much on hold right now. It is incredibly debilitating.
I'm reluctant to go to a regular doctor who will just push some drug down me and mask the real problem. Though it may be my only option. I am looking for a D.O., Doctor of Osteopathy here in San Diego (if anyone reading this knows of one) or in Washington DC. I live in both cities. Hope your situation resolves quickly--please share any cures you may come across. Good luck!
