I propped myself up in bed last night and managed to escape any incidences over night. It seems now that I'm up and about and talking, the mucus is building up again and I already had one spell this morning. :\
I do have a suction machine. It helps quite a bit, but when I start coughing, sometimes it's just too late.
I'm more concerned about keeping food down. I've been doing really good without the PEG. I think I've only lost about 10 lbs for all of treatment. That being said, I have a ridiculously low metabolism.... the one time when it helps, I guess.
Maybe I'll just rotate between ensure and the suction machine and try to avoid talking to much. The talking seems to make it worse.
Thanks to everyone for the tips about propping myself up, though.... that definitely helped.
