Living with a sleep disorder, I'll tell you that sleeping can be very hard. But not sleeping enough will kill you, so you have to make what efforts you can.
And don't make the mistake of thinking you'll be more efficient if only you spend less time in bed. Long term sleep defficiency can force you to be more resilient in your thinking and to get great at scheduling your other habits, but it can only make you dumber and slower at the same time.
Walking dead for sure. It breaks you down from the inside and is not easy for doctors to detect unfortunately. When I first started to reach out for help, they put me on anti-depressants. Sure I was depressed, but exhausted more than anything.
Then they took out the ADD stimulants. Not such a great move when dealing with an insomniac. Sweden lol... "What, you have trouble sleeping? Who doesn't. Go to bed earlier. Oh and take these pills for something entirely different!"
Have to laugh at some things and then just get on with our lives the best we can =)
