Hi Mamakin - great work on your progress so far! You seem like you've been really enjoying eating primal. I can totally relate to that feeling. I would really suggest hiding your scale and only using it once in a while if you have to, or not at all. It looks like it's bringing you down, when you obviously enjoy primal for its own sake. It's quite normal for weight to fluctuate every couple of days, it could even just be water weight. I've noticed 2-3 pound fluctuations between days, when it's clearly been impossible for me to gain/lose that much in a matter of hours. If you're in this for the long haul, forget about the weight, enjoy it, and weigh yourself once in a blue moon - and enjoy the success of feeling wonderful in your body, instead of on the scale.
Hope this helps. Keep at it, you're doing great! The kinks will work themselves out over time.
