Lots of recent studies have shown that coffee is a health benefit if you drink it in moderation.The strong cravings last for several weeks. As I remember, for me, the third week was the worst and then each week beyond got a little, tiny bit easier, but it took three months before I was no longer tempted daily.
I have been a non-smoker for 17 years. I had tried many, many times to stop and had failed, until I got pregnant for the first time. I quit and it really was not that hard, I guess because smoking was simply not an option. I vowed that if I could quit for nine months, I could quit forever. With that said, I have not had a cigarette since then and there are STILL times when I either think "If I were smoking, I'd have one now" or there are times when out of the blue, I think I smell a cigarette and have an instant (although very mild) craving for one. I believe anything that addictive should be illegal.
The caffeine thing is much easier, in the long term. Yes, the headaches are rough but usually only last a day or two and then you're done. As long as you don't start back, you don't have to go through the withdrawls anymore.
I agree with Gryeyes, one step at a time, Honey, one step at a time.
Try cutting back to a cup or two a day.
Smoking has never had a health benefit.
