@katlan @sueinmn I agree with Sue. And I have never heard of bringing of cups and cups. I'm sure there might be some cases but my guess would be a tablespoon, maybe two....it just depends on each person. Some days there's more, some days there's less. I just lie down on my back (postural drainage) and do huff coughing which is just a big push from the stomach a couple of times and that works for me. I have an Aerobika but stopped using it. Nan
