Peppermint can diminish your milk supply though

Apparently a lot of teas 😂 I just looked it up. Green Tea, Ginseng Tea, Smoothies are good, Peppermint tea, Pomegranate juice, Lemon water.

Honestly fruit and water. It will take a few days to get your body used to not drinking caffeine but it will be worth it. I wouldn't stop caffeine cold turkey as that may cause headaches but slowly.

vitamin b12 is good for energy. plus citrus fruits are great as well!
