Sorry to hear you are still having this problem. I don't get much sleep either. Usually go to bed around 2am. Some times don't sleep at all. I have to be up by 4:30 about half the time and about 7 AM the rest. I hit the wall at about 2PM...and really need a nap (but, of corse cannot do so at work). Once I get past that, I am good until I get home (about 8-8:30PM). Still have stuff to do, so can't go to bed until about 10:30 (or later)...but wide awake by then. I am beat at 2 AM and crash easily and sleep soundly. Been like this for about 20 years for me. Did a lot of shift work and all-nighters at least once a week until I was in my 40's. Probably not very healthy (but am seemingly in good health). I do consume a huge amount of caffeine.

When I get a lot of physical/muscular activity, it makes it worse. I fall asleep quickly, but my old muscles wake me up. I bet this is a lot of your problem as shoveling manure and moving stuff is hell for me (afterwards).
