How should I *best achieve* my best sleep?
I sleep most comfortably without any pillow behind my head. – Instead, I sleep with my pillow underneath my knees. <-This way, I keep from turning in my sleep, which helps to control my snoring.
Recently, this setup no longer works! 
I have awoken in the mornings with a dry mouth and a noticed sore (blister) inside my mouth, on the far side of my cheek; where the last tooth cuts the inside of my lip!
What technique, style, device or equipment should I use to help me correct my sleeping-situation?
Testing my preferred firmness of mattress, I sleep most comfortably on a "Number-6"-setting (Sleep-number system(r).
I sleep on a STANDARD MATTRESS PAD. I am told that I can buy a "pillow-firmness device" at my Sleep-number store for $50.00
Please suggest any "other techniques" I can try without having to buy this expensive / high-techie pillow-insert at this ridiculous price.
Thanks for suggestions.
It sounds as though you have several problems contributing to your snoring. By sleeping with no pillow at all you are not keeping your neck in alignment when you are sleeping. Try a memory foam neck pillow they keep your neck in alignment which helps to keep your airway open. Also the biggest reason people toss and turn in their sleep is because of pressure points the mattress is creating. When your body senses a pressure point (which usually is cutting off circulation) it forces you to wake and adjust to relieve the pressure. A memory foam or latex mattress pad can help to relieve these pressure points.
