Been suffering with a cold/chest infection for the past week but noticed my asthma worse through night and having to take my reliever more often. Dr gave me antibiotic today to help. My peak flow is a bit lower than normal - is this usual when asthmatics have the cold? (recently diagnosed and still hate this wheezing, so very new to all this and it's still scary to me!!!) any words of advice as I find nightime is harder to deal with on my own.
