Very good point. Coffee drinker? It takes some experimenting, but suffice to say people that only drink a cup or two a day should try not to have any at all at least 24 hours before a session. People that drink many cups a day, OTOH, should drink several cups before a session. It's what I've found over the years to pretty much eliminate that type of shakes, i.e. shaking while shooting.I don't remember uncontrollable shakes after a shooting session...actually I don't remember a lot of things. I do recall when I use to shoot against a pal of mine, the one who had consumed the least amount of caffeine usually won. Just a thought.
