Milk struggles

Hey mums. I am on meds for milk production I drink blue Gatorade daily I eat lots of fruits and vegetables and definitely meat. I am on some extra vitamins like prenatal vitamins and some minerals like iron magnesium calcium I'm also on milk thistle and fenugreek I breastfeed in the morning and a night and pump through the day. I massage boobies in the shower and i have baths and pump. I drink plenty of liquid. I got on birth control a week ago but it's just depleted more I'm getting 2oz per boobie on my period and 4per boobie when I'm not. I want to breastfeed until after my little girl is two. She has tongue tie and cant do formula. Any other ideas. I refuse to give up but I'm starting to feel like a failure.
