I would wonder if you are holding or positioning your head and neck in a position that causes the tingling, etc. I need to be very disciplined to keep my head and neck straight.

I can easily fall asleep in front of the TV after watching a movie. I need to avoid overly stimulating stuff. I use this as a preparation to go to bed. If I try to go to bed before I have drifted off in my easy chair, I will toss and turn in bed. If I wait til I have fallen asleep in the chair, I can position myself in a comfortable position i n bed and fall asleep immediately.

Dealing with the insomnia can be a job in itself. Finding the right process is a challenge but worth the effort.

My best to you.
