I was digging around on curezone a few days ago and I went back pretty far. I read someone had the same problem, this person was saying something like they would be fasting and lose 0 pounds and then they'd come off and bam, they'd drop like 4 pounds and it happened more than once. I was looking for the post for you so you could check it out but I had no luck. If I find it I'll let you know.
