Hi bigdreams87, welcome o the board!
How long have you been sick, and how long have you been on this protocol? Have you been tested for co-infections?
I am not familiar with Zhang's protocol, but I believe others who have been on it have experienced herxing. You may need to ease up a bit and then resume what you are doing. I think it is a good idea to speak with him.
During treatment, it is good to document your symptoms daily. One way to do this is to list the main symptoms you have each day with a numerical rating of their severity from 1-10. Over time when you review this information, you can see when your herxes occur and how you are responding to the meds.
I hope you feel better soon.
