Asthma attacks in the night help!?

Very common. Night attacks of asthma are common. If they occur with some frequency (more than once weekly, your physician may prescribe a "controller" inhaler of cortisone. Additionally, dust mites are a common cause of attacks. Make sure your mattress in in a plastic barrier type cover. And your bedroom is as free from dust collectors (rugs, stuffed animals, etc) as possible. An air cleaner may also be helpful.
Nocturnal asthma. This is serious stuff. Don't delay treatment, you need a maintenance inhaler and you need to have your lung function evaluated. Get a proper asthma action plan, see an allergist or pulmonologist.
