who rears her ugly head that week or so before AF comes to visit.

Otherwise known as PMS.

Since having DD2 I have had the worst PMS. It's absolutely horrible.

I go off at the most stupid inane things.
Poor DD's and DH get snapped at all the time. While I am going off I am even thinking to myself geee that's really bad why are you going off like this but I just can't seem to control myself.
The swear words that come out of my mouth could make anyone blush.
I really am setting a horrible example.
I'm so stressed out and there is no real reason for me to be at the moment. Life is going quite smoothly.
I want to eat eat eat eat. Especially sweet things which has made me put weight on.

I am really over it. I am normal for two weeks and then horrible for the next two.

The only thing I can think of is my lack of sleep. DD2 is a horrible sleeper. I've had 3 nights full sleep in 15 mths. Most times I am up 3-4-5 times a night with her.

Anyone else in the same boat?
What sort of things can be done to manage it?

I think if I get out for a walk every day it might help me de-stress a little.
Any natural remedies you have found work?
