new work schedule

I started this new schedule today and already its kicking my ass. I think I'm getting old and my body isn't as versatile as it used to be. Anyways, this schedule is one that if you work 9 hours per day Mon-Thur you will earn a day off every other Friday. I honestly don't know if it's worth it. At least not yet. It's an hour less time I'll get to spend with my son after school. I really need to be here for him at this age. I'm conflicted. I had to try it and see if it would work. I don't like getting off work an hour later each day. The reason I have been going in very early was so I could get off early. Now what is the freaking point? So I came home and fell asleep until 8:00. Weee.
