Debbee, congrats on the quit. 1 1/2 mos is great,
Key here, start adjusting your thinking, you must change your thoughts.
The difference here is a physical need (crave) v.s a psycological need (want)
during the first three days to 7 days of a quit, nicotine is falling out of your blood and tissues causing a withdrawl, thus crave, the withdrawl and crave is what is satisfied when you smoke nicotine, it satisfied but immediately begins again until withdrawl and crave smoke, forever.
A Want is a psycoglogiocal there is no physical effects, those are long gone because if your blood has been nicotine free for 1 1/2 months then it is strictly mental, it is a matter of mind and attitude.
I cannot begin to give all the tips on learning patience with your quit, and mental adjustments, I really recommend you do some reading at whyquit.com for the followup education on being able to keep the quit going.
Long and short of it education and attitude will keep you nicotine free.
Best to Ya,
