I'm doing mine in Mexico, I'm concerned about several things. 1) no doctor follow ups, 2) self control, 3) being sick to whatever stomach I have left. I have acid reflux now and am on meds. I can hurl over anything; coughing, dry throat, brushing my teeth. Surgery/anesthesia makes me nauseous and 4) what if I have some undiagnosed underlying issue such as hypothyroidism and I still don't lose like I expect?
