One thing is for certain, looking back I know that I can never have another puff, and wow what a ride it has been, I went through it all, not sleeping, literal pain
in my neck
(from tossing and turning at night), being tired, not having patience for people, you name it!
Hang in there, replace it with exercise and in turn get into the best shape of your life... Turn the (seemingly) negative into a positive!
