If your sleep is broken, you might try another hammock. I'm not saying I know one will be better, but I have heard the DD are pretty small hammocks. Usually, the more fabric a hammock has, the more comfortable it lays. Like I said, I don't know if this is your problem, but I sleep through the night and wake up in the same position I fell asleep in when I hang in my Blackbird. YMMV
oldgringo's reply to my worrying about owning extra hammocks:
How many pairs of underwear do you own? Do you refer to them as "extras", simply because you're not wearing all of them as we speak?
