The Ascaris123 document talks about GERD... and addressing it in the treatment protocol.
Seeing that you are going to try the ALB/PRZ combination based on your other posts, I might suggest trying Mattk3's method of taking the ALB/PRZ with calcium in the form of unsweetened yogurt and taking vitamin D3 daily (carefully starting with a small dose). The calcium and D3 are said to greatly enhance the effectiveness of PRZ.
