Hypermobility?

Hello All.  Just wondering whether there are any other families out there with hypermobility issues and, if so, how they work with these. 

Here we are keen on postural restoration techniques (see Neal Hallinen's Youtube videos if these might be of interest to you, although these aren't specifically geared towards autistic people), plus gentle yoga and polyphasic sleeping (since many of the issues seem to arise during sleep, when posture cannot be easily controlled and sleeping for longer might exacerbate things).

I'm also wondering whether ADHD drugs are helpful or not.  My impression is that, although they can definitely improve focus at the right level, this level might also stimulate the nervous system and make "nerve hypermobility" worse - i.e. the feeling of nerves being out of place and lots of "popping" going on, with quite a long recovery time needed.  Does anyone have any experience of this?  I'm not even sure whether "nerve hypermobility" is actually possible, although this is what it feels like. 

Any thoughts?
