good to hear from you! Congrats to us on making it to day 4 and I'm really glad to see you are toughing it out.
I just got a woke up call to the bathroom. My stomach was really botherin me but after takin' care of business, I'm feeling pretty good. Even though I don't have class til 1, now that I'm up, I may as well stay up. So, I'm preparing myself for the ritual shitty SWF.
As far as the lack of energy situation- maybe, try putting a bit extra maple syrup in each cup? I've been doing that since the beginning (I'm already a thin guy and a bit worried about not losing weight) and I've been feeling really good, energy wise. I think this will give your body some extra nutrients and perhaps keep your energy level up. It's worth a shot.
Keep on truckin'. Once I get my day situtated I'll hit you up with an email and check in.
