I have Hepatitis C with cirrhosis,most days just getting up is hard. A few months ago I quit doing all the drugs "they" were giving me and started riding my bike more. I found that I was feeling better, I went from 10 miles a day to 18. Now I do 30 miles twice a week and 18 a day 3 more days. My wife not only supports my ridding, but yells at me if I don't ride at least 5 days a week. I grow more in love every day.
