Resting in bed for 15+ h sounds like ART to me? Unless you are still doing things during the rest.
ART seems very interesting overall, a lot of success stories as far as ME treatments go, but somehow no interest in it in recent times..
I just had my worst crash ever and am trying to get out of it using ART. Same type of thing, literally lying in bed the entire day with minimal phone use, only get up to use the bathroom and eat meals in bed.
Thanks for commenting on this post/thread. I'd heard about it, and wanted to see it, so I'm happy you brought it to the surface.
