This is what I do when my foot falls asleep. Lay on the floor and elevate your numb foot, rest it on a coffee table or on the arm of a chair. This will make your foot tingle a little bit more and in no time its back, and it isn't as uncomfortable as just dealing with it.
pour a bucket of cold water on it. or you could tickle your heel and make it do a "foot sneeze". hey, so, if i tell you to walk on your sleeping foot and you do it. would that still be considered sleepwalking (because youre walking and your foots sleeping)?
