I went straight by my Doctor's orders. I love the UNJURY protein powder. I was afraid my body was rejecting the band at first becaue I was running fever. It got up to 101 on Sunday (had the band on Friday) but did not call the doctor until Monday and did not see him until Tuesday. I have been taking a strong antibiotic ever since. I felt like a 18 wheeler hit my for about 5 days. I have only had Suger free Koolaid, Instand breakfast, crystal lite. I am beginning to get a little hungry now but it goes away with just a sip or two. I have not been excercising yet--should have started that 2 days after surgergy but felt too bad
