Thanks for the replies, everyone,
Not sure if my personality has changed for better or worse, but sometimes I get very irritated due to minor things, especially when I am tired. I was searching for some reasonable explanation, other than I am a jerk, and thought that the AN, might be pressing on some brain structure that somehow control personality, but it appears from these comments, that this does not seem to be the case for all who replied (admittedly, not a huge sample base).
Since I am on W & W, and taking one baby aspirin per day for tumor growth mitigation (as per the article in a recent ANA newsletter), I haven't noticed any further degradation of my balance or tinnitus issues, so all is good from that perspective. Things could be a whole lot worse from all the postings I have seen on here.
I don't know if any of you saw the school shootings in Marysville, Wa., but that is about 25 miles from where I live. My wife and I square dance in a Marysville school building (not the HS) so it kind of hit home for us. Still no indication as to why it happened. What a terrible tragedy for all involved.
