I can side sleep fine as long as I have a pillow between my legs in my gathered end. I don't often side sleep in my hammock.
Honestly though, most people will adapt to sleeping in a hammock. I'm a side sleeper at home, but in a hammock I kind of just sleep on my back. Even when I side sleep, I always wake up in the morning and I'm on my back. You'll find you sleep different in a hammock.
