I was straight-edge for 2 years till I fell off the wagon for a year and a half. And I haven't had any alcohol or other intoxicants for the month I was training, and I've never felt better. I don't regret the time I fell off the wagon, but I felt like fate gave me the call to arms to come back to the 'edge.
EDIT: And big ups to my riding partner. He's a cancer survivor, talked me into doing the ride, and is awesome. I call him "Captain Jack" because his name's Jack and he was our team captain.
I was more referring to the after-effects of the long bike ride
