The best thing I have done is change the way I eat. I started using the Feingold diet guidelines ( no additives, preservatives, food dyes, etc.) However, lately I am having trouble staying on it...go figure. I feel sooooo much better when I eat clean and eat well.
Fresh air, always makes me feel better.
Excercise. Another one of those things that makes me feel soooooo much better, but I really struggle to do this. I did get some walking DVDs that I can do inside and I actually like them...but making time to do it is my problem. I have a treadmill, too, but my legs feel really weird after I get off that.
I used to journal. A LOT.
I try to get enough sleep.
Now that the kids are older I occassionally have a glass of wine.
I eat. I shop.
