I was 4 hours away from making it a full 4 days. But I just couldn't last. My body just hit the wall. My mom said I looked like a drunk. I wish I could have lasted that 4 hours to make it 4 whole days. But I guess 3 days and 20 hours was good enough.
I have to say... I will do it. I did it once when I was younger, much younger. I will do it again, even in my "pre-old age."
