Alright. So far I have discovered I can knit while taking percocet. At first it was a bit dangerous. All those pointy sticks slipping and sliding and flying this way and the other. Then I managed to remember to grip harder on the needles and a little less tightly on the yarn. And one can become somewhat accustomed to being dizzy and ditzy. It is even amusing at times.
The question now is can one knit while getting an MRI? I don't know if I can lay still for that long without my knitting. I do have wooden needles.
