I'm soooooo with you! Last night, I did something new though. I usually go home, take a shower (since I workout usually after work) and get in my comfy clothes that I sleep in. But last night after I took my shower, I put jeans and a t-shirt and socks on and did some cleaning and some homework (oh, did I mention I am also in grad school full time?!). Then I took my dog for a walk and I didn't have the urge to want to go to sleep at 8:30 like I normally do. Ha! I mean I sleep great throughout the night, but for some reason I feel like I've been run through a pulper by 8:00! I am consciously trying to come up with ways NOT to be so exhausted so early so that I can spend time with my hubby when he gets home from work (he works retail and this time of year, I'm lucky if I see him before 9...)
So, that's my first piece of advice...try not to get into clothes that make you want to head right for bed. Go for a walk if you have a well lit neighborhood when you get home from work.
Let me know if you can think of other tricks, because I'm definitely having the same issue!!!
