It's not perfect, but it works, 5 months tommrow, after smoking for 25 years solid, 30 years total. My life has totally changed for the good. I can breathe, taste, smell, run, swim. I don't stink, my house doesn't stink, my truck doesn't stink, my clothes don't stink. I have an extra 50 bucks in my pocket every week, even after buying all I need and more vaping supplies. The first two weeks are still a *****, there is other addictive material I mean CRAP in those stinkies, and you have to get past that. Add a ton of water to your daily intake, and it's a breeze. After trying every other quitting drug, tool, program you can think of, and I tried them all..this one worked...Spend no more than a carton of analogs and give it a shot, what do you have to lose??? Oh ya, your life is all.........GOOD LUCK!!!!
