Raw garlic is the cheapest and most effective parasite remedy for me. It not only works in the intestines, but also blood, and the lymph system where larvae and other things live. You have to take it steady for a continued period of time, and eat very light taking the garlic on an empty stomach. It will make you smell badly, but I got the impression that you don't work outside the home?
Some people report brain fog and other issues on garlic........well YEAH, it's killing parasites all over. I get brain fog too, weird dreams, and other die off effects until the garlic cleanse is over and I feel great. I never knew it's blood purification or lymph clearing properties until recently, I just knew it worked for me. and now I understand more why.
You can get an enema bag at walmart for $4.99. I have all the big chains here, and walmart is the only one who has the bag. But I made my own using a strong and easy to clean gallon jug, put a hole in it at the bottom, bought a roll of silicne hose, and used the clamp from an old enema bag. I just secured the hose in the hole with silicone caulk and let dry every night. This way I can throw away and make a new one if I feel this one is getting old. I use empty Crystal Geysier water bottles, they have a handle on them to hang.
However, what you are doing is getting worms out, so do all that too. They don't come out like you described until they are threatened and dying, so when you find something that works, keep it up too!
