Well, I am so hungry I feel crazy. Does that help you, lol?? I too, can wake up hungry. I like to eat often and plenty. I can't ever skip a meal, and can hardly skip snacks! so this has been hard. as for low fiber, I haven't even thought of it. I've been relatively stable, this is a "better safe than sorry" test. Let me tell you---you will REALLY appreciate food after this. Even stupid food you were probably sick of like rice. Oh, glorious rice. I will post later after I've started the actual "prep". I am 10 min late. Oops! People aren't meant to only consume liquids! It's just not right!
