Most definitely. I'm usually on a "high" after rehearsals, which can last more than several hours, and it often takes me a couple of hours to wind down before I can sleep. There are exceptions, though, depending on just how tired I am that day. Our few gigs so far have been much shorter (and end a lot earlier than our rehearsals), so falling asleep after one is usually not a problem as it's already been a few hours after playing that I do go to sleep. In either case, once I do fall asleep after a rehearsal or a gig, I find that it's a better sleep than most nights as I am pretty much exhausted once I do wind down.
I also practice on the pads most nights of the week, but that doesn't seem to have any affect on my sleep.
I wish I could say I have good sleep hygiene in general, but my sleep patterns are all over the place from one day to another. It's been like that since I was a child. I feel I would be more productive in life if I did have a better sleep schedule - it's one way I differ completely from everyone in my family (who are all up at 5:00am everyday).
