Jamie already mentioned how hard Saturday was, but I'll add some detail.
I stayed up late Friday night and slept in Saturday. I then waited too long to eat my first meal and I think that is really from where much of the difficulty came. I felt like each meal I ate from there just took me from being crazy hungry to pretty hungry and I just couldn't catch up with that satisfied feeling I craved. Add this to the fact that this was my first day doing this from home and didn't have the bustle of work to occupy my mind and was in a place where I could, if I wanted to, pour a bowl of cereal at any time to put me out of my misery. It was tough. Fortunately, I pulled through. I did end up having to drive through the beginnings of a snow storm to buy some dill pickles (I admit I giggled a bit as I was walking to our door with a jar of pickles in hand like I was carrying a bag of Reese's).
So how is it going so far for me really? I'd have to say, so far so good, but if the hunger doesn't subside, I have a hard time predicting sticking with this for the long-term.
On the plus side, it is REALLY nice to have relatively great tasting, pre-prepared, quick snacks that I can just throw in my laptop bag and have when I need them. I've also packed a few spares in my bag and office just in case I get stuck somewhere without my food when it's time to eat. The bars, in particular, are great. I've also enjoyed the honey mustard pretzels, brownie, and ziti.
Also, I already feel the difference of eating smaller quantities of food at regular, short intervals. I feel lighter inside. I'm not sure if that makes sense, but that's how it feels. I'm not tired after lunch at work and I feel more energized in general. It helps too that I'm already down 9.5 pounds!
So, I'll stick with it for this next week and see how it goes.
