I’d concentrate on the cigarettes before the coffee….
DON’T TRY TO QUIT BOTH AT THE SAME TIME!
As a matter of fact, forget about the coffee for now and just quit smoking.
The only way to quit is cold turkey. Seriously. After smoking for 15 years, I tried the “weaning-off” approach, and it never worked. Stop smoking, altogether ASAP, and you need to find new smokeless places to hang out that you didn’t go before. Get yourself a box of nicotine gum and chew.
Everyone’s different, but after about a month…only a single month, you begin to lose the urges, somewhat, and you fill that time with other more useful activities.
You’ll wonder how you ever found time for puffing in the first place.
