I feel bad when someone tells me they can't get comfortable. I slept in a tent from 1978 - 2007. Got a hammock last year after Perkolady told me how much she loved hers and it's sooooo much better for comfort! I absolutely love it.
Last time I was out in my Hennessy, I slept right through a rainstorm that woke others. I also use earplugs. Guess that's why I didn't hear rain!
I hope you find your sweet spot real soon. It will be worth it!
