99.99% of the time, I do my full routine before bed (I have my boyfriend trained to bug me about it when I'm tired - "Darling, don't you dare get in that bed before you wash your face!"). The only times I skip are when I have been partying a wee bit too much and simply cannot stand at the sink long enough to wash it off. I HATE waking up with mascara smears, eyeliner bogeys, and foundation flakes, so I have to do it, no matter how tired I am, because sometimes it's harder to deal with removing stubborn makeup in the morning than it would have been to just force myself to wash it off at night.
