I did the same as Ren, i just stopped..One day i thought ang on a moment i am not enjoying this any more, just back from Holiday with loads of cheap backy and papers...chucked the lot in the bin and never had any..I think it was the same a Phill, 12 years ago..Does not bother me when mates come around and smoke. I never tell them they should stop, tis up to them.
Rock on Phill.
