I'm not sure if you ever heard of lactation cookies or lactation brownies but they did wonders for me! I used to drink the tea as well i loved it! and for some time I took supplement pills to increase supply like when I got my menstrual back and noticed a drop in supply. I will attach some websites where you can get the emergency lactation brownies and cookies, you'll come across many positive reviews as well.
