Pleased to hear you got some good news wonko - I'm moving from IB to ESA soon, and am not looking forward to the process.
I'm currently reapplying for DLA too, but unfortunately I keep getting better. In a bit of a catch-22, the additional money from DLA has made managing my fatigue a lot easier and allowed some real improvements... so I think that I may now be inelligable. It was nice while it lasted though, and has given me more time to read up on CFS research and realise how dishonest a lot of the early advice I was given was, so I think that I'm in a better position to manage being poor and ill this time around.
Good luck with your DLA, and the support group.
PS: This is probably a stupid question, but was there anything useful about your WRAG meetings? From what I've seen of the DWP, I'm dreading them.
