It is obvious that none of us are the same, I believe we all take different meds. I was started on theo-24 and terbutaline last year as well.
My doctor perscribed aminophylline as an alternative. It is an older version of theophylline. Since on aminopyhilline, i now sleep through the night, no cramping at all, and way less leaks. Also, a lot less bitchy when I stopped taking terbutaline.
The strange thing is that aminopyhilline costs $21.00 a month at 1200 mg a day. That is without any medical coverage. It is negligble with medical.
So ask your doctor. This may be a an alternative med for you. It is very interesting when you look up the two on the web.
