Maybe you should ask your doc about nausea meds they can help you. As far as Protein they made me sick too!! I am 5 weeks out and I can tell you it does get better even if it does not feel that way now. It is all a learning process and just take it easy on yourself. Your body has gone through a big change. I think you are right on target for walking. I pray you get better soon. Take care God Bless!
