One of my boobs is drying up and the other is perfectly fine, please help!

So one of my boobs is drying up?!? I literally pumped out 1/2 an ounce while my other boob produced 5 ounces ( 20 minutes time). The crazy part is it's her favourite side b/c it has a slower let down and she can eat more leisurely on it. What do I do?!! I don't want to feed from one side only. How do I increase milk on that side?! Please help!
