Can try chicken essence too, my Friend? I never tried this before myself but I heard it works! For myself, I used to make myself a cup of Milo with oats when I was hungry after pumping! Cos quite a number of ppl said Milo with oats is a milk booster! One stone kill two birds!!
Try taking Al-Kurma. You can get them online from Dhaqq Nutritions... It’s dates juice.. It helped me to boost energy :)
