I'll deviate from other posters and say.. that AF, she's a b&^%$!!!!

when i got af back 2 months ago, i felt the same way. i've always had the hormonal drag and moodiness with my cycle, though.
I'd suggest high calcium & magnesium foods, and say it will get better in the next few cycles. also, for future thought: i had my placenta encapsulated, and i've taken a few with AF and pre-AF, and it helps so much. it's really amazing.
in the same boat, and my goodness..it's so so so hard to cook with a little one. we're really trying to do some food prep all at once, toss some potatoes & sweet potatoes in teh oven whenever it's on, chop everything all at once, cook meat ahead of time and freeze.. all those little things make throwing together meals easier. a spinach & chicken quesadillia with beans suddenly becomes a 5 minute assembly rather than a cook the chicken, cook the beans, etc. project. my dh is able to do lots with cooking, and grilling is pretty quick, too. what we do at this point is have one of us entertain the babe while the other one cooks. nothing could get done otherwise.
the crockpot is a bonus, too, as is doing a whole chicken or turkey breast in a crockpot or dutch oven and then using that with different ingredients all week. hugs, mama!
