Have you considered fasting - even if just for a day or two to see how it goes? My daughter relapsed a bit and I had to keep her home again today. I only allowed her fruit and nuts, and she's much better and I plan for her to return to school in the morning.
But I did without food all together today, because I developed a nasty sore throat. I simply didn't eat today, and drank LOTS of water, and everything is draining just fine now.
I had extra vitamin C, and allowed myself to develop diarrhea, and then cut back on the c, (I only ended up having like 4 or 5000 mg but I may have needed so little simply because I didn't eat).
