Maybe I'm wrong here, but this feels like giving medical advice based on very little hard evidence. Considering I have a loved one with MS, I find such advice sickening. You see this with many terminal diseases.
Terminal disease is a fucking terrible thing. It makes people desperate in every sense of the word, it makes them grasp at anything. Flippantly mentioning a few things that 'might help' is basically saying. "Hey, here's a thing that maybe means you won't die / suffer as much from dying". Making such claims lightly is (excuse my language) being a fucking asshole. You are getting someone's hope up, only for that hope, and a little piece of that person with them, to be smashed to pieces when it turns out to be wrong. Moreover, you are telling that person "don't accept your fate, here try this". Acceptance is needed for a healthy way to process terminal disease. 'Advice' like this fucks with that in a big way.
Don't overestimate your own chances of being success at the expense of a dying person please.
(I know, harsh words. But I needed to get this off my chest)
