I get your point Non and at first I believe it is very important to focus on AV and create the seperation to ensure you are aware of it. This is where I got into trouble. It was difficult for me to recognize the sneaky thoughts that would pop up throughout the day as AV and by evening I was "white knuckling" and not sure why. Once I discovered that the subtle thoughts (that beer on TV looks really good or today is a day I would have enjoyed a glass of wine) added up to make me unhappy I had to take a different look at them.
However, I understand you to be stating that they are not affecting you so "should you be leery of every thought that may be AV". I dont think so. Besides with your BP in place you are not going to drink no matter what thought sneaks in.
