OW! I Think I hurt Myself!

I've been a bit hyper the past few days..and of course I head to the gym to work it out of me so that maybe, just maybe I can get to bed before 3am and without an ambien which makes you want to eat (last night I had two handfuls of ginger snaps around 2am maybe more)... I did 8 miles on Sunday in 2 hours (all treadmill), 2 miles in 30 mins on Monday, and today I did 9.25 miles in 2 and a half hours. I didn't feel it till I had driven to the pharmacy and got out to walk in the store to pick it up..and now..just ow. Seriously. Ow. My goal is to be able to run a 7 min mile. So some days I work on my speed and days like today I work on my endurance. Anyways I've burned about 2,200 calories in the past three days. I've been working out non-stop for a month and my friggin scale won't budge past a certain weight, which I will not disclose. My Dr. said 10 more pounds would be more than ideal.. I'm thinking 20 would be optimum. But the scale is not playing nice. I know I know..the fat is turning to muscle which weighs more than fat. Save it, I've heard it from everyone. Arrrgh!
