1% milk is what we drink. 4 gallons of it a week between myself and the boys. I rarely drink it before a gym work out, it tends to make me tired. I believe milk has that stuff in it that turkey does, making you naturally tired. I've discovered that if I stay away from caffeine (except for weak cup of tea in the morning before my commute) and drink less milk, I tend to have more energy, and "wake up" more efficiently. I've not had more than a cup of coffee per month for over 5 years now. I don't miss it and I feel a helluva lot better without it. I still love the smell of it though.
