Following some heated debate and such forth with Skybird and some other chap who wound me up...
I thought, this weekend, instead of smoking, I wouldn't. Don't ask me why, just felt I had to prove a point. Well..... had a go. Friday came along, normally 2 or 3 menthol cigarettes get smoked then. Nope, didn't touch one. Today, I actually, and this is true, forgot I was meant to be abstaining and I smoked my cigar as per normal, about half way down I realised I shouldn't be doing this.
Which has led me to realise, smoking is a very automatic thing! You just do it without even thinking.
