Experiences with waking up at 5:30 AM for a productive workday?

Maybe you could use the time after 2200 when everybody else has gone to bed and it's all quiet. Depends what kind of stuff you want to do of course. Performing woodwork in the middle of the night is not likely to be appreciated by those asleep!

Somehow I have found morning hours most productive. I have no idea why evenings don't work as well. If I need to get something done, I better force myself to wake up at 5 am (and try to get at least 6 hours of sleep).

You may or may not have insomnia but it sounds like you do have a delayed body clock. If you are able to sleep 0200 to 1000 with no problems then I suggest that you don't have "insomnia". Melatonin is not a sleeping tablet, it is a body clock modifier. Taking it at the wrong time could make things worse.

This is a bit off topic so lets not delve too deep to this subject. Natural rhytm for me would be around 30 hours. Sleeping is never non problematic to me. Falling to sleep is always problematic. Also, light affects me quite a much, so summers, with their 20 hours of sun light are nightmare to me. Anyway, thank you for your insight.
