There is no substitute for sleep, period. You are sleeping through your alarms because you are exhausted. I would venture to guess that you have a very full academic/social life that is forcing you to spend ridiculous hours in the studio. This kind of timetable may be necessary here and there, but not as a long-term strategy. Your body/brain have no time to rest/regenerate, and you will wind up getting sick a lot. Why do you think people who work swing shifts are more likely to have health problems (I know, you are young and made of rubber and magic, until you aren’t)? The body’s rhythms just aren’t well suited to fighting “dark=sleep”.
Ask yourself:
- Can my course load be lightened at all? Drop a class, take it P/NP?
- Am I working as efficiently as I can with the course load I am taking? You may find that your “study time” includes a lot of dicking around that you weren’t even aware that you were doing.
- How many clubs/EC’s do I really need to be involved in? If those are taking time that is pushing you to such late hours doing schools work, they aren’t worth it.
- Am I carrying on with this kind of schedule because I think I have to? Sometimes, competition among students (or the desire to please a boss or teacher) is such that you want to always be the one who worked the hardest or was there the longest. Work smarter, not harder. Otherwise, the task will expand to fit the time allotted (in your case, almost through the entire night).
Do NOT rely on a friend to wake you up - that burden is not theirs but yours. Plus, you will come to rely on it, and then one morning, they too will sleep in (or forget, or not be there), and you will not only be late for class but resent the friend. Two of D’s roommates promised each other to wake each other up (one is notorious for sleeping thorough whatever alarm system she has; the other is just burning the candle at both ends is constantly exhausted - sound like anyone you know, OP?) - both slept through their respective classes and were not happy with each other about it.
