Is this normal? I lost 6 pounds in 3 days!!?

I went to the hospital monday morning with what turned out to be a bad kidney infection. They kept me there for most of the day cuz I kept throwing up the pills they gave me. I'm out of the hopsital now and taking medication but the meds they gave me (anti-nasuesa combined with vicodin) for the pain have prevented me from even being able to eat the foods they recommended like jello and soft stuff to work my way into solids. When I checked the scale today it read 113.5 when i had weighed 120 when i went into the hospital. Is this normal? Could my scale be wrong? What can I do to get back into eating- will I just have to wait till I finish my medication?!?

Your scales are probably accurate. And it is normal to loose that much weight when dealing with an illness. Personally I have lost over 10lbs while being sick for a few days.
