I am a BF mom too, I fed my middle girl up till 3 weeks until the next one.(2yrs) I have found that nursing tea by Yogi is the best for me, you may want to take a green drink as well. I would also call the manufacture of your vitamin and ask if its ok to take while BF maybe stay on your prenatels for now. Some herbs can decrease milk as well, cilantro, parsley, kale?, some meds, I had a cough the DR gave me Musinx and he knew I was nursing, the pharmacy said it will dry me up, so I stopped. But it sounds like your doing what you should. I'm telling you the tea works so good for me, I would drink like 3 cups a day or until it kicks in. and it taste good too. You know that you can from your first so don't give up! You said you workout alot, you might want to take a break to see if that is what is causing it.
