I haven't done any active attempts at LD for many years now and the last time I did it was only for a few weeks before I got busy again.

The other day I was able to rest well and get some LD in without much effort. Now I want to be able to get into the LD state more regularly.
In the past, I had the most success when I could dedicate an extra hour of sleep that I didn't really need to get fully rested. I would often wake up to an alarm after 4-5 hours and be awake up to 15 minutes with a focus to LD afterwards.

Any tips for attempting LD when you might not be getting enough sleep to be fully rested most nights?
