Just turned 50

Well it's day 76 today and almost 2 weeks ago I turned the big 50. My reason to quit 76 days ago was I didn't want to be 50 with a smoke in my hand and I want to run.  I can happily say I have accomplished both of these things and feel great, but although I hardly crave any more, once I'm on my 3rd glass of wine the urge is almost too hard to bare. I will admit that on several occasions I have given in to the urge and have lit up 1 cigarette and then I realise I don't want to smoke but I just wish I didn't give in in the first place. I consider myself a healthy non smoker but wish I was strong enough to just not have that bloody one cigarette......I hate it so why have it?????
