One thing I will say is that if your other half says he can smell it on you, and he WILL smell it on you, don't try and convince yourself otherwise, he CAN smell it and they day he finds out you've been telling porky pies, he'll be very hurt. I found the pills you put under your tongue, that dissolve very slowly, helped me the best. I smoked 40 a day for many years and thought I'd never do it. You've done it once, you know that you can. Good luck!
I'm sorry if I sound severe, but this is so important for you!
