Thanks Alison,
It looks like there are a few things that keep cropping up. But maybe to keep it simple I might start with a good quality multivitamin, keep up the the Glucosamine, Condroitin and MSM that I'm already using and add some Chromium and Omega 3. Maybe throw in some Acai Berry and try to use a bit of cinammon in my cooking.
In addition to the above I shall be on a low carb diet (I love this type of diet anyway, and have never really been a big fan of processed carbs) and get my exercise regime going properly.
I've only been on this regime (low carb diet - not supplements) and testing for the last 3 days, but I'm already seeing benefits. My waking BG levels have dropped from 9 to 7.8, and if I plot a graph of all my rest results, the trend is creeping down nicely. I've had a few hiccups with food experiments (muesli and stoneground wholemeal bread for example), but testing, testing, testing seems to be the key to enable me to identify the offenders and cut them from my diet. My fingers are a bit like pincushions at the moment though, but I consider it a small price to pay for knowledge.
I've really stepped up the exercise - either swimming 1Km or cycling 10Km every day, although as I have costochondritis (or something very like it), taking proper exercise really causes me a lot of pain, but I'm working through it and hopefully getting some fitness back will help with that too.
