how do you know when your immune system is balancing?

I am treating myself and not seeing any more doctors and I'm doing alot of guessing but I think I've been right so far. I think so because everything I'm taking is working and I'm getting better fast. But I'm wondering about the immune system. If cfs people have th2 overactive and need to boost th1, how do I know when it's happening? The only thing I can think of is my food allergies would get better. Has anybody done this with tests showing that it happened? If so, what were the physical changes that occurred if any? karen
