I tried the zyban when I tried to quit the last time, it seems I'm one of the small number of people that it doesn't affect.
Plus when I fly I wear a patch, chew nicotine gum and have a nicotine inhaler. Even if it's only a 2 hour jump to Spain.
Also tried acupuncture, not painful, more uncomfortable.
I'm thinking of going to see a hypnotist, it's the only thing I've not tried...
