Please don't do it! You'll be just as fucked off, but smoking while you are!
(I'm an ex smoker - had a 7 year break, went to a party where people were smoking outside, cadged a fag, took a few drags and thought 'this is revolting'. Bit later and drunker, cadged another, it wasn't so revolting and I was back to a 20 a day habit for another 10 or more years. It is so very easy to get hooked back in)
