My husband has been sick with Bronchitis for a week he was given a prescription for z-pack and cough syrup, He has had watery stools today, which he was warned about due to taking the z-pack. For the last 3-days he hasn t been able to sleep he has the need to move twitching. He stopped taking the cough syrup 2 days ago as he thought that might be the cause, He has lost 13 lbs in this one week of illness. I think maybe dehydration may also be a problem. When we called the Dr. we were just told to take the cough syrup(w/codene) during the day.
