Well many people seem to reckon that they need some crutch like patches or
sweetie things to tail off. There are two problems, one is the hand habit
and the other the addiction, trying to tackle both at once is too much for
some people.

I read somewhere on the interwibble that moderate use of the "hand habit"
can make you slightly short-sighted.

Is there any truth in this?
