Thanks Leemack.

Now that I think about it, I had 2 periods in a normal 30 day cycle when I weighed 150 lbs....This was after not having any in 9 months (during which time I was losing 10 pounds).
As my weight has shot back to 160, the periods stopped....

It is crazy how differently my body behaves at 160 compared with 150- my insulin dose goes up a good 25%, the periods seem to disappear. It just blows my mind that I can be well within my BMI range and still experience these problems....

Anyway, I am back on track- no more cheats and watching calories as well is important for me.

This morning I weighed 157.5, so things don;t look so bad after all.
