1. If there is no right censoring (and it appears not), I would use
lmer on the awakening times, glmer on the FullyOriented variable. That
is, I agree with Burt.
Another option is GEE models
2. If you want to use a Cox model, then you can
a. Add "+ cluster(id)" to the model statement. This adds a robust
variance, and is closely related to GEE.
b. Use coxme to fit a mixed effects model.
