Bayliss...No I don't this it bizarre.. I feel similar to you. The evenings are long (because I was usually out by 8:30). So, like you indicated, it is a period of adjustment. I think after a while you will get use to the change, however their will probably be times when you are bored. But that is life. We will have to learn to deal with it without numbing ourselves with alcohol.
I am starting to go to movies, and have started exercising in the evenings. The weekdays are not so bad, weekends are harder. Are there any hobbies you would like to explore? Is there a fitness facility close by you can use?
My thoughts for what they are worth.
