Annie, I've always had a hard time losing weight and running high mileage. I just feel sick and seem to lose all my willpower. On the plus side though, I find it almost impossible to gain any body fat when I'm doing the high mileage, no matter how bad my eating and I've had some real doozies to test that theory! Now my weight goes up and down a lot, swinging from mild dehydration to fluid retention after a hard run. I'll routinely gain up to 5 lbs of water weight after a long run or a race, which goes away in a day or two. Maybe something similar is happening to you?
I was supposed to run yesterday, but just couldn't bring myself to do it--too tired and just came down with a really really bad case of the blahs. But I got up this morning and did the run I was supposed to do yesterday, 3.5 miles, 40 min, most of it at about an 11:30/mi pace, with a nice warm up and cool down thrown in for good measure. It was perfect--low 50s, rained last night so it wasn't too dry, nearly full moon lighting up everything in the pre-dawn. It was still hard to do, but I'm real glad I went. I feel like I've done something really good for myself today.
Everybody have a good one!
Anne

), but it was just going terrible. I just decided to take it easy, jog nice and slow and take some real generous walk breaks. I did the same miles, burned the same calories and ended up enjoying it a lot. Only 20 min longer too--good investment. Doggie was happy too since she gets to do a lot more sniffin' that way. 
... except that my MP3 batteries went dead on me!! What can ya do...
I hated it as a matter o' fact ... I average running 3-4x/week between 5-8 klicks... I go to the gym regularly too 4-5x/week working a different body part every day ... today I ran to the gym 2.5k, did back and bis, then ran back ... sometimes I take the long way back but today time was short ....
