It is hard to give up, You need a lot of willpower to do it, I gave up for 2 years once and then started again, It is something I regret doing I don't know why I begun again, I quit with the patches, I chewed gum to take the urge away, I want to quit again as I have an awful cough but I think it eases the stress for me (excuse I know) but it is something that keeps me sane at times.Maybe have a word with your GP? There is so much help now to quit smoking.
