I have been plagued with cold feet and toes all my life. After completing the Seven Steps to New Life routine the tops of my feet would be hot to the touch, but the warmth never seemed to make it to my toes. I eventualy discovered that rubbing my feet as part of the harvesting of the qi was quite helpful. I held the bottom of one foot with one hand while vigorously rubbing the tops of the toes with the other hand for a couple of minutes. Afterwards I could fall asleep right away with nice toasty toes. After a few weeks, the problem seemed to be much less, so maybe it has something to do with opening energy channels. Hope you are staying warm.
