If I have been awake for three hours after going to bed
, and I went to bed at
0930, I know I still have enough night
hours left to get some sleep
. This reduces my anxiety level tremendously while I'm awake. On the other hand, if I go to sleep
at, say, midnight, and I don't fall sleep
for three hours, there are not too many night hours left; thus, increasing my anxiety exponentially.
