I am just about 1.5 weeks out and so far i haven't gotten sick, just a little nausea and tired, eating more and I assume still healing. I have had a little hassle with sleeping positions at night but i think for the time that is normal. I was like you thinking what am I doing to my body? The odds are you will heal up fine and adjust--bodies are amazing at that. Think of the positive health benefits you will get and just follow orders!
