Increased appetite

I am just under 3 months postpartum and the last week or two my appetite has gone crazy! It isn’t just that I’m craving certain things (though I am) but that I get so incredibly hungry that I feel nauseous and light headed even if I’ve eaten something already. I exclusively pump and my son has been going through a growth spurt but I’ve had issues with over producing so I haven’t had to increase my pumping to make up for his extra feeds so I’m not sure that’s what’s causing it. It’s gotten to where my stomach is constantly growling and I wake up to feed my son in the night and can’t go back to sleep because I feel so nauseous. I’m eating a normal amount and trying to include lots of protein but nothing seems to work.

Any experienced mom’s have any insight?
