Have slept for a week in my first hammock (https://www.amazon.com/Vivere-Double.../dp/B004YJCP7O) and it feels pretty good so far.

How flat is one's body supposed to be? Is it straight as a line or more like on a recumbent bike? I also woke up today with a weird tingling feeling on my left foot that's lasted for several hours, like a nerve was impinged or something. Could this be because I'm not laying flat enough? I'm sleeping off-diagonal like in the intro to hammock guides.
