What's Your Best Laxitive?

What RRR said in the first post used to happen to me when I smoked.

I'd go out to the garage, fire up a cig, and then get to work.

Just about the time my hands got real dirty, I'd feel nature's call.

I finally started to wonder if it was the cigarette.

Stopped smoking in 2005, and that problem went away.
Yep smoking, coffee and alcohol all did it for me.
