an older model of feeling depressed had it this way: external event happens...then you have a thought about that...then if the thought is negative, you feel angry (outward manifestation) or depressed (inward).

What if, instead, the process is more like this: a brain chemistry change occurs.... then you 'feel' depressed... then you go looking for rational reasons for why you feel that way to explain the sensation.

If the second model is more accurate, then part of what happens when we feel upset with (whatever) in LCing is that we are experiencing a common (if maybe not normal) brain state. We probably experienced it a lot, and we probably are used to treating it with carbs, which do give relief, temporarily. The problem is, in the long term, they deepen the depressive state at its chemical roots. Staying off carbs gives you a chance to recover to physical normal...and if you don't in a few months, maybe there's a serotonin problem or something else that would respond to other treatments than LC.

rationally, you must know that a six pound loss in two weeks is very very good. And yes, weight gain at TOM is common. I quit weighing 10 days before, myself, and don't weigh again until it's all behind me!

ketosis during menses, however, is very uncommon. Try again in a week, at a different time of the day. As Nat says, the ketostix won't tell you everything (and some people, they never tell anything!) But I suspect in a week, they'll say something different to you.

HTH! hang in there.
