I've struggled with that before. Especially night time was hard for me. It seemed as soon as I got anywhere near horizontal - here it came! Sometimes I coughed so hard I would choke and gag and still would not have gotten any relief. A few things have helped me. 1) Adding pulmozyme to one treatment a day consistently.2) Getting some concerted exercise. I'm a mom of a 2 year old also and I thought that life in general was enough to consider exercise, but I have found that actual concerted focussed exertion is what I need. You can be creative. I've made up some games that involve my daughter, so it's exercise for her too (bu she thinks it is play) and it helps me get what I need without a gym and babysitter fees.3) I take one Mucinex (guaifenesin) tablet twice a day. It's 12 hour effective and I take the regular one (not DM) so it ONLY has the expectorant in it. It helps my cough to be more productive with less work, so I end up coughing less often and for a shorter amount of time. Let us know what you end up trying and if it helps you.
