I gave up consuming caffeine. I was a huge Diet Coke and coffee drinker before i started working out for the HIM. I used to drink more than a 2-liter bottle a day and 4-5 cups of coffee through the day as well. I gave up the Diet Coke completely but i will have decaffenaited coffee a few times a week. What's the deal with coffee? is it recommended not to drink or is it acceptable? i read some other forums where some triathletes drink coffee before the race! What's the deal?
