I'm 3 days post-op for the first 3 days everything fine, but I keep waking up after 5 hours of lying down feeling sick, I've started walking daily 1 mile to alleviate the sickness and gas today I'm down on my fluids, as I've been feeling ill, however, i will try and complete my fluids today - start weight from the initial 2-week pre-op diet was 20.08 so far I've lost including pre-op fluids 22 pounds, there was really no pain after surgery.
