Hey,
congrats on the best decision you will ever make for yourself. the key here is you!!! It is not impossible to be around a smoker and quit, I had a long pause 2 yr 8 mos in 2000, during most of that my wife smoked, I was away from it the first week out of town, and when I got back it was not too difficult to stick it out,
Then two years and 8 mos later started back and took another 4 yrs, to get back to the quit, this time tomorrow will be two years free,
Just Know in your mind...72 hours free and all nicotine is out of your blood... after that it is all head games...drink lots of cranvberry juice or orange juice, the acid helps flush the nicotine out of the blood. keep your blood sugar level by eating a little something every couple hours.
keep in mind caffene will be multiplied in effect so watch the intake or you will end up buzzin on caffeene which makes you seem even in more nicotine withdrawl...
check out whyquit.com for lots of good tips,
Best to ya, ...RJ Free at Last...2 yrs tomorrow after 32+ of killing myself to the tune of 2 packs or more aday
