I know its hard when you are desperate for sleep but maybe think...
1. You will not upset or offend anyone being tired
2. You probably will not end up in jail as a result of lack of sleep
3. You cannot damage your liver from lack of sleep
4. You will not loose your job from being tired
5. You will not loose your family from being tired
6. You are not likely to loose your wealth from being tired.
7. You are not likely to loose your home to being tired.
8. Its not very possible you can die from being tired
But you can loose all things and could die if you continue to drink, just like I could.
Stick with it, you are doing great
My best to you
