Another ex-smoker here. 42 years of puffing away and I have tried every stopping aid under the sun. Trouble was I didn't really want to give up. I felt good, certainly enjoyed smoking, and thought that not having a morning cough like most smokers, I wasn't effected by the nicotine drug.
Two years ago I got a mild stroke, luckily with no detrimental aftereffects, and that was enough to make the decision for me. For one week I went through panic attacks, sadness, tiredness etc. but with the aid of patches and support from my partner, I made it. I now look at smokers and know how many feel, wanting to stop but thinking they can not.
My partner was ok with me smoking too, until I stopped and she immediately made the house smoke-free, so she was probably never really ok with it.
I still think of a nice puff after dinner, and eagerly walk past the 'smoking-outside -the-door brigade, hoping to sniff some of that evil smoke. But after two years it is easy to say no and I'm pretty sure I'll be a permanent ex-smoker..
As a bonus, your taste buds will improve in one week, in two weeks you will cough up the gunk from your lungs, you will have more 'puff' (pardon the pun) when walking/working, you will be able to instantly detect anyone who smokes, and best of all.... you will be doing your new grand-daughter a big favour.
If you do decide to give up, good luck.
