Congratulations bkjames00,
It's a great feeling to have your first 100 mile century under your wheels! As noglider points out, eating and drinking are absolutely essential on longer rides like that.
I rode my first century back in '78 and have ridden countless others since; sometimes on organized rides other times on my own. Each time it's an adventure. We've had a very mild (and too dry) winter here, so I've ridden five centuries and one double century so far in 2014. Commuting is good training for centuries; centuries are good training for doubles!
