I took a sleeping pill and went to bed at 9 with the alarm set for 5 and an open mind about whether it really would be a good idea to get up then; but there is a non-fee-based Beast session on Tuesdays and Thursdays at 6am, and the rule for the Beast is that when you miss class, you make up the work. And I did feel ok when the alarm went off, so I came downtown for class and then did a spin on my own afterward.
