My machine has user comfort settings. One of those is to adjust the ramp-up time. I set mine to zero - GIVE ME MY AIR!!! After that change I was able to easily fall asleep. It was difficult prior to that. I can also adjust the humidity setting. I had to increase it a notch because I woke up in the morning with my nose running and sore - which means I was dehydrated (yeah, that wasn't how I interpreted that symptom). After those two changes I was able to fall asleep quickly and not wake up with a sore and runny nose.
