Keep it up Amos! On Monday and Tuesday I was taking groups of teenagers up Pen y Fan, Cribbyn and Sugar Loaf - some lumpy hills in Wales - and felt smugly pleased that I was sounder in wind and limb than they were, and that the smokers among them - even at the age of 19 - were in bits.
You'll be amazed at how much fitter you feel, and how much more you enjoy the outdoors. And, should you get cravings for chocolate, cookies and carbohydrates, head up the nearest hill instead; the endorphins a bit of exercise releases will see off any craving.
As for nicotine itself - I still pop in a piece of gum when the craving gets unbearable (usually after a good meal) and do enjoy the odd pinch of snuff.

And well done, Liz! Castle Hill is steep even without a giant on yer back!
