I often don't sleep much. I roughly follow your 'don't stay in bed for more than 20 minutes if you're not sleeping' rule. My reasoning is something like, 'if you're lying in bed and _trying_ to sleep, it means your body needs something else more than sleep, such as, moving around, sitting up, managing anxiety or other emotions, etc.' Then I come back later when I don't have to try.

How do you think that fits in line with your understanding of the research?

(Also, your $45pm price point is way out of my budget. Maybe if I was managing less well with my own methods I would be desperate enough to spend that much)
