To some slight extent, I believe, I experienced the same pains in my boyhood, before I smoked, and I am not an absolute stranger to them yet.

They were most frequent in my smoking days, but I have no other reason for charging them to tobacco.

Possibly a doctor who was himself a smoker would have pooh-poohed them.

Nevertheless, I have lighted my pipe, and then, as I may say, hearkened for them.

At the first intimation that they were coming I laid the pipe down and ceased to smoke--until they had passed.
I will not admit that, once sure it was doing me harm, I could not, unaided, have given up tobacco.
