It has been three years since my last treatment and for the most part I feel very fortunate. Taste, saliva, etc, are probably back to 85% +/- of what they were. But in the last year, or two years post treatment, fatigue and cognitive issues have started cropping up. I'm only 53 so don't think age is the issue. My memory is not what it used to be, and all to frequently I really struggle finding the right words to say in a conversation. The fatigue is such that many nights after I get home from work, once I sit down, it is very difficult to get up. Only a year and a half ago I was actively involved in sports so this is a big change. I would be curious if anyone else has similar symptoms so far past treatment.
