I've been increasing the amount of time I sit. Partially this is to prepare for the 50 minute intervals that they do at Valley Zendo, and also because I feel the increased time gives my mind a chance to wear itself down and get into the Zazen properly.

All this is great and working well just having one semi-serious problem.

My bottom leg falls asleep!!

So much so that I can't stand on it after finishing the session. I know this will make it difficult for me at the Zendo, I won't be able to get to Kinhin when the rest get up to do it, Should I be doing something differently I've been told to make sure I sit on the edge of the zafu, but this does not make a difference. Any suggestions of things I can try?
