I am officially on day one of the USD.  This is anything BUT simple.  I'm wondering if I can really really do this.  I know we're supposed to start on a Sunday but Sundays are just NOT good days for me to start a diet.  I don't work.  I'm a SAHM  so there's really no excuse as to why I can't put in this extra effort and focus.  I'm having some trouble with it too....oh, I'm miserable right now.  I just finished drinking my very first US Shake and although it wasn't exactly pleasant tasting and quite gritty, I forced it down...and once I got to about the bottom 1/4 cup of it I realized that all the flax/borage oil settled to the bottom.  I was very close to losing the entire shake that I just consumed but somehow I've managed to keep my composure.  Now I have a terrible, terrible case of heartburn/acid indigestion and I've taken 2 natural acid reducers (with ginger, fennel and chamomile) but it's not helping and the thought of purging this out of me is starting to sound like a good idea.  Anyone else with this much trouble with the shakes?  I probably need to post this on another board but I thought I'd ask while I'm here. I'm hoping it will digest very soon and I won't have to put up with this misery much longer.  This is why I'm so hesitant to continue this diet.  So far, not so good.
