I am terrible at going to bed at the right time and getting up! I hate sleeping, but I understand that it is an important part of being. Do you have a smartphone on the android network? I've recently downloaded an app that has improved my sleep quality and length and I'm sleeping much better. It's called
Sleep as Android and what it does is notify you when it's time for bed, you can play a lullaby to relax you and put you to sleep, it tracks your sleep (via movement and takes recordings if you sleep talk etc), and it gently wakes you in the morning. It's brilliant and it has helped me so much with getting off to sleep, which is the hardest part for me. (If you aren't great at waking up either, you can set it to make you play a game to turn of the alarm!)
As for the running, you really need to build up to it. If you haven't run much, then I think it will take a little longer. I'm currently building my stamina and muscles up to be able to run for a solid 30 minutes, and then I'm going to take on a fun run/marathon. You need to start small and build up depending on how your body is coping. I suggest that you start by walking, increasing your speed until you are near jogging. What I have done once I could walk fast for 30 minutes (I only do 30 mins a day) was go for a short run (a lap around an athletic track) at a slow pace. I did that for a week or two and then increased it to 2 short runs with a break in between, and then 2 short runs together.
As I said, it all depends on what your body can handle. If I remember correctly from High School 10 years ago, when you run you put 7x (or 10x) your weight onto your knees when your foot hits the ground. For me, that's about 1000 lbs of weight each time I run. I'm not sure how exact this is, and it wouldn't take much to research, but the the point is that your knees have to carry the impact weight too.
You are about the same weight as I was when I started and, I'm not going to lie, it is difficult to run long distance without feeling sore and tired long after the work out. However, my muscles are a lot stronger now and at -15lbs I can do 2-3 laps in a row (3/4 of a mile). I have to rest for a minute to get my legs back afterwards (which is why I split my runs up with walks), but it does get easier.
I hope this made sense! I'm trying to condense and sum up everything I've learned in life and my own experiences
