It's been two weeks since I quit smoking. I waited this long because I was so affraid of gaining weight but I decided that if I wanted to train for this marathon that I had to get serious. So my problem now is that I am so worried about eating too much that I am starting to restrict again. I've been training for a marathon and was doing well with eating. But now I'm starting to lose weight fast and my training is already being affected. This is so annoying. I either smoke and run slower because of my lungs, or don't smoke and run slower because I'm not eating. Does this even make any sense at all? I'm just going to have to stop being so paranoid I guess. I'm running 40 miles a week, it's ok if I eat a little more right?
