Starting 24 Hour fast

I am starting my 24 hour fast at 7 pm.  I have fasted before so I know what to expect going in to it.  I will drink water throughout the day to stay hydrated, but other than that I will avoid all food and beverages.  To prepare I ate a huge pasta dinner to get a lot of energy.  It will be tempting to eat when I start to get hungry so my biggest challenge will be avoiding restaurants and other places where people are eating.  I imagine it will be the hardest around lunch time tomorrow, but I am confident that I can make it 24 hours without eating.
