Have you ever used a fake fatigue tactic in a poker game?

[Mike_25]

Have you ever pretended to be more tired than you actually were as a tactic to make your opponents underestimate you in a poker game? I'm not advocating being dishonest, but as a pro player I do admit I have occasionally exaggerated my fatigue to reduce others' suspicions of my hands during long sessions. It can be an effective trick to trip up careless opponents, though it sits in a gray area ethically for me.
