Something it's less about duration and more about waking between sleep cycles rather than in the middle of one.
The maker was too tired to use the right one. And yes actually that's been suggested before. I really should get a test done.
I'm not sure if that's available here or not. I did always wonder how different it would be when sleeping in an unfamiliar environment.
We're you having trouble sleeping or did you find it impacted the quality nonetheless? Because I usually have something playing but I'm out in a few mins.
