The mother of one of my daughter's school friends was diagnosed with it. She lived about 3-4 years but in the end, as it was explained to me, she had life extending drugs which she just chose not to take when life became unendurable and she then passed fairly quickly and peacefully.
Horrible to think of having to take that decision.
You die due to not being able to breathe. That's isn't 'peaceful', that's asphyxiation.

I believe that once she decided to no longer take the drugs that were keeping her alive she was given something that allowed her to pass peacefully into unconsciousness before she passed over.
