Got Beer?

My milk supply has plummeted in the last few days.  I have no idea why, but it's very frustrating.  Lulu is sucking as hard as she can for very little.  I can hear the swallowing slow way down, and the sucking speed up and intensify.  Then her little face turns bright red.  Then she starts punching my chest with her little hand.  And then she starts wailing.  And this is after five minutes of eating.  I obviously don't have enough for her!

So I asked my mom if she had any tips to get my supply back up.  She told me to drink beer!  So I happily cracked a cold one.

Has anyone else ever heard of drinking beer for milk??  Does anyone have any other tips for me??
