What is the reason that Dr Klimas and Cheney tell us to take drugs like imunovir in a pulse method? I have been taking it for years now, did have a !00% improvement which I thought was the imunovir, but have now had a relapse. Initially before the first improvement I took it every day for 18 months and carried on for 2 years while well. I then continued to take it at only 2 per day for a couple of years while I was well but after 4 years of wellness I've relapsed again. I have been taking it 6 per day every day mostly for 18 months ( taking the odd weekend off). I am still housebound and having relpases after exercise. I asked about this on another thread but I can't find it again - perhaps someone answered but there is nothing showing on an icon to say I've added a post. So I'm trying again. I'd be very grateeful if someone could tell me what is the reason behind pulsing as my Dr doesn't seem to know.
