Welcome Shuddhagiri.
No doubt, anyone who has at least some passion for their sadhana would like to do more of it, especially when time is so precious. The system here is designed with that in mind. Have a look at
L172 and
L227 as just two examples out of many other discussions that deal with setting up a practice session in a way that fits your lifestyle in the best way possible.
It is a common struggle over here, so it might help to say you're not alone in the quest to find ways to sleep more efficiently. I've repeatedly favored practices late into the night at the expense of sleep, hoping they can make up for it a little which they do, but otherwise have been paying the price that I'm not sure can be justified. "It's a marathon,.."
The importance of sleep is emphasized, since it is a necessary component as much as any other. Some people are naturally able to sleep much less than the average, with one person I know by association averaging 4 hours per night, while others like myself have very low tolerance for it combined with a sensitive sleep schedule.
As it is now, there can be much gratitude for coming upon such a system that is mindful of everyday life demands and making use of them to our advantage, as with grounding and integration. A steady, more or less predictable daily life also makes regular sittings possible. Finally, the practices themselves alter the nature of sleep. For me, it has brought more coherent thoughts in dreams, and I see how it would be possible for this to deepen over time, though it too must be done gradually and in a way that's in tune to the changes as they occur naturally.
