Not the voice! I lost my voice in rush, as in screamed through the first 4 of 7 parties the first day and started to lose it, sounded like a man the second day, and was silent by pref day. Thankfully the girl who rushed me in Zeta the first day (who ended up being my big!) saw me again the second day and just laughed histerically at the fact that I couldn't talk over then insanity of the party. I'm glad she found it amusing.
But seriously, hot green tea all the time - my rho chi ended up having to bring me some in between prefs! haha, glad you're having a blast!!!
