I'm currently experimenting with a Thermos (and it must be a Thermos, in my experience this is a brand worth paying the premium for) of tea/coffee by the bed, made just before sleeping. The minimally cognitive task of sitting up, unscrewing and pouring from the flask is enough to blow away the cobwebs, and the instant reward is enough to encourage me to start. It doesn't need to be a caffinated drink, but it does seem to make the motivation stronger.
