A total human sleep cycle is about 90 to 110 minutes. Most important is that you'll feel most groggy if you wake up during the deep sleep parts of a cycle. I've found trying to set my alarm in about 90 minute increments (from when I think I'll fall asleep) helps a lot. For me, that means basically either 6 or 7.5 hours of sleep on weekdays. I also agree on the alarm. I use my phone, and have it set to gradually increase volume with a gentle noise - I change it occasionally, but typically choose something like birds chirping or piano music.. so long as it doesn't have abrupt loud sounds. These two things have helped me significantly with feeling decent when I first wake up. I'm still not a "morning person" but I'm at my, let's say, "average" level of productive by the time I'm at work in the morning.
