My problem turned out to never be CFIDS at all. I was in benzo withdrawal, and just didn't know it. The only reason I "recovered" in April 2010 is because I restarted the evil drug (Ativan) that caused it in the first place. My mystery illness returned when I stopped the Ativan this past March 2011. I guess it felt like CFIDS because benzo withdrawal causes widespread inflammation and immune dysregulation, so the Tagamet helped calm things down in my central nervous system. Reading my last post explains a lot. If only I had known then what I know now. You can't take B vitamins while in benzo withdrawal, that's why I got worse. I'm being tapered off Valium now, still having withdrawal seizures, and experiencing all the "CFIDS" symptoms that were never caused by CFIDS at all. If doctors had never treated me with any drugs at all, I would be 100% healthy today. Be careful what you take for your illness, you could easily end up like me. I'm off work, going on disability, and not expected to be back to work till next Spring. Losing my home, losing everything. All because doctors tried to treat my "CFIDS" with antidepressants, benzos, and stimulants. A dangerous combination, and I don't know if the seizures will ever stop. Not worth it.
But for what it's worth, the Tagamet still helps the sickly feelings that are very similar to what you're all experiencing. It really controls the severity and duration of the withdrawal "flare-ups" which are still caused by the same mechanism... elevated cytokines and immune dysfunction. Good luck, everyone.
