When words/thoughts enter my mind during an IS or reading such as "I wonder how long I have been
IS"..."I'm hungry. What should I grab for dinner?"....etc....

Totally unrelated to what I am doing at that moment, these thoughts are
big-time distractions. I have been on a quest for absolute concentration to
the task at hand and rid myself of these distracting thoughts during IS, or
whatever.

Any thoughts or suggestions?
