I usually snack on exclusively fruit the day of a journey. I have heard around the forums that 100% fasting is unnecessary and perhaps even reduces potency. I find some fruit in the tummy helps keep the plant oils and tannins and such from having such a debilitating effect on the gutz. I am a vegetarian/ basically vegan usually, so my diet usually never interferes with how strongly I purge. I would recommend not eating meat for a few days prior to the drinking. IMHO, of course.
Look forward to yr results!
EDIT: O and take it easy on cheese. I find cheese to really mess with my stomach's resistence to the brews emesis... could be totally psychological, but there you have it.
