In the almost 70 years that I have been around I have experienced the inability to go to sleep quite a few times. I found a remedy for his problem in the 60's when I was traveling around the country. If I didn't go to sleep within about twenty minutes after laying down I would take a couple doubles of Jack and roll a fat one. Usually I went off to bye-bye land right away.
Sorry, but while I don't do any of that nasty stuff anymore, the old partier in me says doing that then going to sleep is a colossal waste! Why not stay up and enjoy
OP, it may seem like a really bad idea to dive on no sleep, and it may lead to problems. If the dives are easy and shallow then it may not be a bad idea to dive anyway provided you can function normally, most adults can do so with no problems if it is only one night.
As others mentioned, schedule dives for the afternoon, or if the boats often run with a slot open you can start waking early on your days off and making diving a spur of the moment decision. That way you never know at night whether you are diving or not the next day.
