I took a contracting job where I'd travel for two or three weeks at a time, often working long hours. This would usually take me from a spot where weed was recreationally available and ubiqutous to impossible and impractice to get. The two vices ran together for me.

After sobering up while away, I realized how much of a drag these things had been on my well being and resolved to just give them up, or at least try.
