yeah, hammock comfort at the start can be sort of elusive. the forum does a good job of praising being up off the ground, and offers a lot user experience and what's worked for each individual hanger.
there is no plug n play method to it. the physics and personal comfort range, in addition to hammock style, build and way its hung all can be determining factors in side sleeping comfort. a hang one night at site A might be awesome, while the next site may not have the perfect trees and the way your hammocks hung might affect comfort. - not to mention how tired you are, how you normally sleep, etc.
i can attest though i hate being on a wet ground, in a small tent, or under a tarp. the hammock is fun to mod and make your own. it provides great shelter at low weight. but most importantly it gets most of us out recreating in nature.
