No idea but I can do the same thing... The other day I realised I went without eating anything o_0 so I'd gone about 30hrs without food. I do try to be conscious about eating though to set an example for DS, and at least try to snack on fruit if I'm not feeling like anything else.

Hasn't had any effect on my supply that I have noticed, and DS is still taking the boob roughly 4 times a day plus 1 overnight
