However, when I started again,it was much easier than i thought. Soon, I found I didn't need to walk any more and I found I could run further and further.In the end,I was able to go for a 10 km run without problems. I've lost almost 20 kg and I now weigh just 80 kg. I feel so much better and I'm planning to run a marathon next year. These days,instead of spending all my money on cigarettes,I spend money on going out or buying things.
