More tricks to suppress?

My entire pregnancy I didn’t have much change to my boobs. I had always planned to formula feed so I thought maybe I was lucky and my supply would just never come in.

Today is 4 days post C-section and I feel like I got implants over night. I’ve taken Claritin and used ice packs and of course wearing sports bras to compress. Any other advice? I’ve heard B12 can help? Any vitamins or teas?
