Someone, I think it was H. Clark, said that you can expect your allergies to be gone after 2000 stones. Apparently you are not quite there yet, have patience. I have done 16 flushes and still have skin problems, so I know how you feel. There have been significant improvements, but sometimes I wonder how long it will take.
Can't help you with allergies, but I started to get more stuff out per flush when I began to eat olive oil and turmeric daily. Both are good for the liver and increase bile production.
