Humaworm is very effective if you stick with it. Just because you don't see "worms" does not mean they have not been broken down or clogged in your system somewhere and have not surfaced. I am on my 6th round of Humaworm and I have made great progress but I still feel some parasitic affects but no more crawling in the throat or tummy as it use to be. I was seriously infested according to my stool sample results. I had ascarias, candida, giardia lambia and liver flukes! I was a mess!
You have to remember these things did not show up overnight, they've been in there a while so it will naturally take a while for all of them to be dead. Slow and steady has been my approach and it has worked so far. Getting a bug zapper on eBay for like 10 - 15 bucks made a huge difference. I know it seems hopeless in the beginning but believe me it does get better. Happy healing!
