Milk, bottles, formula, problems

So

In addition to the many health and feeding problems baby has been having, my supply is gone ( pumping and galactogogues arent helping..) he is also adamantly refusing bottles (weve tried eeeeverything so no advice plz). I cant offer my breast more often bc just getting him to latch on one side is hard enough.

Im just giving formula via syringe butttttt he "might" have food allergy (hence health problems) so i can only give alimentum. Alimentum makes him gag and cry though cuz it tastes like pet food.

Since his health problems haven't resolved after cutting out dairy and soy and wheat (next are nuts and eggs), and were in an emergency situation, should i try regular formula?

Sighs. This is all too much and we're struggling so bad and doctors haven't been helpful
