If you have a sensitive gut you should take 1/4 tsp of MSM mixed in a glass of water with a packet of emergen C. This will heal your gut and protect the lining, I was able to even eat very hot spices without any irritation.
Also mix in some l-glutamine.
Get a very high quality MSM.
Aloe Vera juice is very healing aswell.
Even if it's hard, try to stick to the programme so that you target the larvae, adults and the eggs, they have different stages of life.
