I have had CFS for nearly 20 years, and for 19 of those years was able to control it with LEM, then AHCC to the point where I only had a very minor relapse once a year. This fall apparently the AHCC stopped working, as I've been battling a replapse whose severity has varied since August. I went off of the AHCC completely for a month (since there was a time several years ago when I became immune to the LEM, and by going off of it for a month, it once again worked after restarting it a month later), and started taking Transfer Factor Essentials which I did 2/day for 2 months. Jan 1st I decided to try plusing it by dropping it completely except for 2/day the last two days of the month. In Dec. I started taking the AHCC again and was much better. By Xmas my relapse returned in full force and I'm still battling it. I started taking the Transfer Factor Essentials again last week and am also taking TF 560, 2/day presently. I have never been able to find a doctor anywhere near central Illinois who is familiar with CFS. Therefore, I have had no blood tests to determine specifically what I am carrying other than the initial test 20 years ago which was an EBV blood test which showed past EBV infection, but not active. So I'm working in the dark as to which TF to try. I have printed out the post from here which shows what some of the TF products target, but all are not on the list, such as the TF Essentials. Also, last week, after reading Rich Carson's post, I have started juicing. What does one do about juicing when they are away from home for several days where there is no juicer? Is it effective to make the juice ahead, freeze it, and take it along? Any suggestions as to how long it takes the TF products to have an effect, knowing that it varies from person to person? I have also gradually added OLE, which I tried for a few weeks in the fall and I've read that it is one of the products Rich uses. Any suggestions you might have I'd appreciate hearing! Thanks.
