If your baby is exclusively nursing what makes you think you are drying up? Once the nursing and hormones etc evened out with me it didn't seem I was making anything as I no longer felt the 'fullness' yet she was eating well, full, and was passing BM's and urine so I knew she was getting enough food. Also her weight was a good sign as it was going up. You may already be doing this but things to remember - drink A TON of water - even if you don't feel thirsty, down a glass of water. I think I drank two gallons a day (at least it seemed) as I was so thirsty plus I knew it would help with production. There are other things like eating oatmeal, ensuring you're eating a balanced diet, etc. Other people may suggest some vitamins/supplements but I never tried them so I won't offer that suggestion since I don't have experience with it.
