I like working out in the mornings. It is tough but once I got into the routine it got easier. I get up at 5am and I'm at the gym by 5:45 or so. I have started going to bed at 9:30 instead of 10:30 or 11 like I used to. Makes me feel old but it's for a good reason at least.
Exact same boat. Feeling old going to bed so early.
