how to avoid giving off tells?

I've recently read over Mike Caro's book of tells for the first time. Very good book, I usually spot one or two of the tells per session now. One topic it doesn't address is how to avoid giving off tells yourself.


Personally, I have a very hard time being comfortable when I bluff. Throwing the chips out is easy enough, but I seem to go into this guilt state right afterward, feeling awkward even pulling my arm back after the bet. I suppose this is a good thing, as it prevents me from trying to bluff very often, but I also feel like it is preventing me from bluffing occasionally when it would be profitable to do so. A good observant player may be able to see my discomfort. Anyone have tips for how to get rid of this problem?
