Is it hormonal??

I remember some people talking about how a we lose a lot of weight, hormones are released and we can become... edgy.

Here lately I have just been off. Edgy. Crabby. Reactionary. I don't know if it's outside issues (work, economy, news) or if it's my weight loss... or just me.

I usually don't feel like this for anything more than a day or so, and usually in reaction to some outside stimulus. For at least a week, though, I have been feeling like a rubber band wound too tight.

I don't know if this is normal as we lose a lot of weight (not that I've lost a "lot" yet), or if I just need to recheck myself and figure out what it is. I don't like this one bit.
