Antibiotics

Me
Dr has got me on 2 antibiotics and I feel like doodoo!! :'( I got asthmatic bronchitis and sometimes have asthma episodes which I use an inhaler for. The antibiotics are messing with my stomach, often feeling nauseous and very tired, dizzy, and drowsy. Anyone know how to alleviate some of these miserable feelings?? I know they are probably side effects but they feel worse than the actual sickness. :(
