when I went to give up smoking I decided I would do the patches - I could only afford one box - but in Boots they just laughed at me and said you can't give up on one box if smoke as much as you do.
I ended up walking out that shop and have never smoked since. I did it without anything - well I did have lollipops
You can do it - you just need to stay focused and realise even with the tablets it will be difficult at times but the end reward is so much better - now when I tell people I used to smoke they say no - I would never have thought you ever smoked! makes me pleased especially as my sister used to call me fag ash annie cause I smoked so much! LOL
and no I never get any cravings for them at all - just prepare your mind for it! and you'll succeed!
