Thanks for the response Hando & Irish (from before Xmas - sorry bout that).
I've been smoke free since 2nd January this year!!! Was a bit of a struggle there for a while, the sleep thing really did my head in there for a while, but getting through mostly now.
I will admit that any number of mental issues have reared their heads in the last month or so as well and I have contemplated returning to the dark side but vigorous exercise certainly puts paid to that quickly. I credit this kind of activity for keeping this streak going so well.
It's onwards and upwards!!!
