I'm glad that you went to see a sleep dr for your problems. However, you don't know if his plan would work because you weren't able to stick with it. Why not go back to him again and tell him what happened?
Insomnia is very hard to deal with, and it's so tricky because as soon as you begin to worry about it, you're lost. I do best when I'm able to convince myself that it doesn't matter how much I sleep on a particular night. Have you considered napping in the day?
