I think what concerns me is that I don't/didn't feel a 'click' like, hey, I made changes, and 'click' they worked, (welcome to the machine age, huh, where our expectations are instantaneous) and that there is a family history of arteriosclerosis (hardening of the arteries) and I'm concerned that could be part of it -- which is why I am going to get a checkup. In the meantime, I just wondered if anyone else had ever experienced what I have. I don't miss the upset and anxiety at all, for sure. Thanks for replying.
