I'm feeling much better today. The past few days I went back to gluten free Paleo style eating which seems to help. I still don't feel like an energiser bunny but will be able to get on the mat and shake my yoga tail. I have learned my lesson, no sugar binges! I realise that with whichever connective tissue thing I have it won't cure it, but it will I hope make day to day life liveable.
Right Primary Series Ashtanga time (or at least as far as I can get through lol)
