22 years ago I went on a health kick and gave up smoking, booze, coffee and sugar, all cold turkey, then got seriously into mountain biking and ended up with nearly $3000 invested in a bike and rode 5-40 miles everyday for years, spring, summer, fall & winter
I was lucky and never gave a 2nd thought to the booze, smokes or sugar, but giving up coffee really bothered me. I went to see my doctor about it and she said not to worry about it, because the smokes were the big one and go back to coffee if I wanted.
And 2 years ago I also gave up salt.
Still off all the bad stuff, but no longer riding and still loving my coffee.
