Myesthenia Gravis commonly is a cause of waking up with the inability to breath. I have heard that propping up your pillows so your head is not flat when you sleep can help those with Myesthenia Gravis.
I think one place I read that info was at http://www.MyestheniaGravis.org
There is also http://www.braintalk.org and there is an MG area there. You can post to others with MG.
Dear Allison,
I'm sorry to hear that you're having these health problems. What is mg, which you mentioned in your post? What has your doctor said might be the cause & what have you been evaluated for? Has p-o-s-s-i-b-l-e sleep apnea been discussed? Do you have asthma or other lung condition(s)? Are they under good control? Work with your doc(s), and please, please don't a-s-s-u-m-e that cancer is involved. Whatever is causing you to wake choking needs to be thoroughly investigated & controlled, so you can sleep as soundly as possible & wake rested. Good luck & please get help.
Aloha,
