about 5 mins into it, I got this tingling, itching, stinging discomfort in my calves and feet that would not go away and was greatly distracting me. I carried on for half an hour with this going on, but it got it the point where I could no longer carry on. Tim, last night I experienced the same phenomenon you described while doing my delta wave meditation. Itchy calves. I tried to ignore it, because to move is to break that most delicate delta state. I realize now that it was the blanket on the lower half of my body. My body was generating enormous amounts of heat and the blanket was making my legs swelter. Could this be the source of your problem as well?
