I took a long time to get to sleep, slept poorly and intermittently, and had a hard time waking up until I was diagnosed with sleep apnea and got a CPAP machine. Now I just pull the mask on at night and I'm out within a couple of minutes. I also wake up suddenly in the morning, get up, and start my day. Much different from the endless tossing and turning to get to sleep and long drowsy sleep-ins in the mornings. Sometimes I'll come wide awake in the middle of the night. No problem, get up, read, or surf the web for a while, then go back to bed. Sometimes you need more sleep than usual, but sometimes you don't need as much.
