I questioned the OP's sincerity in quitting from the beginning. I obviously don't know the guy. Maybe he is immature and doesn't have his priorities set to be successful. Maybe he has an addictive personality. It appears his weekend of hard drinking is more important than quitting smoking. That seems like where his head is at the moment. I hope that I'm wrong.
I know it took me over a dozen attempts to quit over a 10 year period of time. I tried nicotine gum, patches, prescription drugs, and hypnosis (twice). I wasn't successful in quitting until two things happened spontaneously in my life.
The week that I tried my first e-cigarettes, I experienced a life changing event. My mother found out she had cancer, found out a few days later that it was terminal, and passed about a week later. She was in her 80's, seemingly in good health and playing piano for her little country church. It all seemed to happen so quickly and her passing really hit home of our mortality on this planet. It finally made me realize that if I continued to smoke cigarettes that I would follow my mother to the other side. I convinced myself that I would be successful by using vaping to stop smoking.
Now 7 years since my last cigarette thanks to vaping, I still wonder if it was just a coincidence that I began vaping around the time that my mother died from cancer. Regardless, I think it took a life changing event for me to be successful.
I'm sorry to hear of your mom's passing (I know it's been a while but my condolences anyway)
For me I had a life altering situation going on as well.
The doctors had told me back in 2008 that I would die if I didn't quit smoking (throat covered in precancer cells..) but no matter what I tried I still couldn't quit..
by 2013-2014 I stopped being able to breathe, lips turning blue from simple housework etc.
My breathing was so bad it was terrifying - literally feeling like I was suffocating - it was just terrifying..
My husband smoked, some of my SILs smoked, there was no escape from cigarettes being around me, in my face.
But the terror of what it feels like to be suffocating is truly life altering, and I was able to have the mental strength to quit in a houseful of smokers.
But it took something truly life changing, life altering, to sit with smoke in my face and say I wasn't going to smoke.
This OP? Who knows...
