Luckily I went through a similar experience in college, so when I got rid of the alarm I slowly but surely looped around a bit, until I got the napping right.

Luckily I went through a similar experience in college, so when I got rid of the alarm I slowly but surely looped around a bit, until I got the napping right. However - then I started a job where I had to travel between time zones, and I still haven't figured out how to get the body to know that it's traveled quickly other than mealtime & nap manipulation the day before, and even then I still need alarms.
