What happens when the milk runs out?

When I was in the hospital, the nurses and doctors always said how breastfeeding was better for your baby. What happens when the milk runs out?

For the past two months I had no problem supplying milk for my little boy... actually I made so much that I had to freeze a lot of it. Unfortunately, I have no more frozen bottles since I am not making enough milk. I eat right, stay hydrated and pump when I should, I am just all out. I feel so bad about it too. Today I was feeding him his formula and started to cry. I felt I needed to apologize because I couldn't make the milk he likes to eat. I know he's not crazy about the formula- he makes a face and turns his head away.

Ever since I have started giving him the formula I have noticed that he has become much gassier and slightly constipated. So what did I do? I switched the formula. I chose something that was for sensitive bellies and so far that seems to work for him. With the new formula he is not as constipated which is good and he can tolerate it well (that means not too many spit ups!) .

I still feel bad about not having the milk for him, but I have to look on the bright side of this.... at least I found something that he will eat that helps him grow. That is all I can ask for right now!
