It looks like I may end up being one. My right breast has tanked and I have done everything to try and get it back up but LO just does not want it anymore. The left side is nice and full and produces wonderfully with a great letdown speed ( both used to be too strong and now the right side is like molasses). I didn't think it was possible until reading the below blog.
I had OVER supply for the first two months and I got that worked out but then at 4 months I had a cold, LO started sleeping through the night and got AF back- both boobs tanked but with herbs, tea and lots of water, I got my milk back but the right is just lagging. i've been super lopsided for a month now which is annoying but I can get over it if it means that I can continue to nurse LO.
