Well, I don't know anything about the smoking part as I've never had a smoke in my life, so I'll let others tell you how hard/easy that will be.
I'm trying to make a change in my own life with eating better (I've had a couple cheats already), and exercising to make this body healthier. Unlike quitting smoking, it's costing me a bit more money, but whatever. It makes me happy
Hope you can laugh about this later & wonder why you didn't do it years ago.....as I sometimes do.
