I know this is a very old post and maybe nobody will see it but just had to say something - new on here, am 46, started to get some symptoms so went to see doctor and she suggested this website - although I'm still in denial (am toooooo young !!). Anyway, she also nagged me to give up the smoking and drinking the amount I was, and somewhere on this thread I read about couch to 5k, never heard of it before so did some investigating ..... anyway, I am now 8 days smoke free, 8 days alcohol free, 8 days caffeine free and have started jogging - a few days of my body wondering what the beejessus was going on but am hopeful !!
