There is nothing from the level II material that comes to mind.
I know that some have reported the be energized after doing the active meditations. Personally, I feel serene and calm after any of my meditations.
One thing I had noticed in the past is that when I was regularly doing a lot of meditation each day, was I need for less sleep. I would wake earlier that I had planned but was fully awake. For me this was only a matter of an hour, so I used it to start my morning earlier.
Other sleeping experiences I have relate to starting a small universe meditation, when I go to bed. As with any meditation, I start with making a request for how I would like the universal energy to shape my life. I do the meditation with the intention of it continuing after I drift to sleep.
At times I've awaking much too early in the evening. At those times if sleep doesn't return quickly I will do the above small universe meditation with the intention of falling asleep. Remember, to make your request and let it go. Don't keep checking to see if you're getting sleepier or not. Just make the request and do the meditations. It works quite well for me.
Of course when my practice is solid, I don't have the sleeping issues.
I choose the small universe because it opens the channels and promotes the flow of qi. Also I can get quite hot when doing breathing universal energy, which doesn't help with my comfort and sleep goal.
You are perfection,
