I can so relate to you. If the "grumpiness" is because of the diet, it WILL get better. You are probably super addicted to carbs and in that sense satan has got a hold on a part of you. But even though I've only known you a few days, I know that you will succeed!
OK...I was just praying for you and I had a funny picture! I saw you doing pushups, and struggling. Then, I saw a dove come and hover over you and all of a sudden you were doing pushups easily with one hand! LOL! So, I believe God is saying, "Trust me, my kid...it's so much easier than you think. I am with you through it all. I know that you want so much to please me and I love that. You are my precious daughter and I will not let you fail. I love you so much!"
When I was struggling once, yello reminded me that God will not allow us to be tempted with more than we can bear. It is so true.
Now, the dark chocolate thing is supposed to be for P2. If you can eat it and it doesn't set off cravings, then I guess it is OK, but I'd be careful. What I did a lot in P1 is sugar free hard candies. But, be careful because the tasty ones are made with sorbitol and some people will get intestinal problems with sorbitol.
Praying for you! Keep going!
I am off to Ottawa now. I probably won't be home tonight. My dad hasn't left for Florida after all so I will stay with him tonight and come home tomorrow.
