Are you unable to pull all-nighters? If you're inexperienced, then I would recommend one bottle of Bawls (only one!) and intermittent sips of coffee during the day, along with a serious dose of stubbornness. Body bullying works in theory, but if you're not determined you'll be out like a light by two in the afternoon.

Why is the switch depressing to you? A few days ago you were talking about how you're ready for school and it'll be nice to not be on a full-time lab schedule. Did you change your mind?
