Any SAHMs out there?

Angela
I was originally planning on going back to work but since I was little I have always wanted to be a stay at home mom. I believe it is possible with my husband's income that I can be. He said that if I can figure out the finances and it will work for us, I can be. Otherwise, I can work part time on the days that he is not working. (He is off Mon-Thurs.) How was it like going from 2 incomes to 1? Any advice? Resources? Useful websites?
