I have loaded my two days and will start P2 tomorrow, wondering how this 500 cal will go for me. I actually kinda noticed today I was a little moody. Tonight when I put the kids to bed my youngest kept getting out of bed and I had no patience. I already can tell I will have some crazy mood swings. I weighed and I'm up 3.6 lbs for my 2 loading days.I guess this is good.
