hi, I ve been having this problem for a week now, but I get it every now and then. here s the thing, my stomach will growl, and I feel super hungry, but whenever I get something to eat, I can t finish it, and I end up gagging and coughing for like an hour. also, I get major headaches, and I have no energy throughout the entire day. I just want to sleep all day. is this normal? or is there something we wrong? please help
