Good luck with it Julian, you can do it. I used the patches I'd tried the lozenges at first and they were horrible so went to the doctors and he gave me the patches. 4 weeks on the top strength, 4 weeks on middle strength then 4 weeks on the weakest one.
I'd tried a couple of times before but it didn't work I even went to the doctors and had hypnosis, but since using the patches last month was 7 years since I smoked. I smoked a lot shop bought and roll your own, I was 16 went I started and in my 60's when I stopped so I'd been smoking a lot longer than you so if I can do it I'm sure you can.
