For me, it is inhaling that is difficult. I think the exhaling is more automatic. If I am lying down and not using my cpap, it feels like all the gravity in the world is pressing on my chest and I can't inhale to get any air. Fortunately, this only happens if I am having an exacerbation of the mg. I find if I sit up and lean forward when having the problem, it definately helps with inhaling and after 10-15 minutes, things seem to settle down.

I would try to get my ivig as soon as possible. I go every 2 weeks and when I try to stretch it out to 3, I start having problems.

Good luck!
