Smoking...my worst habit

So, I am down to my last cigarette.  I bought this pack a week ago today, so that's really good. BUT...I want another pack.  I didn't go with my friend to the base just now, because I know I could get my brand at a cheap price.  So I left myself having to walk (in the freezing cold) to a German store and pay way more if I want to get a pack.  Smart, huh?
