This thread is cracking me up.

Speaking of nervous energy, when I did my first century, I wound up going twice(!!) at each reststop. Having Mexican food for dinner the night before probably didn't help. Luckily all the reststops were in nice public parks that had clean bathrooms with running water instead of funky porta-potties.

A few years back I read an article about the Atkins diet that said constipation was a major side-effect of the diet. And yet there were people who thought it was a great diet anyway. Where I come from, that's a deal-breaker.
