As I wrote previously, I was on Metformin 1000mg for a "diagnosis" of Type 2 diabetes, which after advice on here, I found out that it was the culprit in malabsorption of B12 (mine was 199 and insufficient). With Drs agreement I stopped taking the Metformin and started supplementing B12, Selenium,Vit C, Magnesium,Folate, D3+K2. I eat Liver to address slightly lower Ferritin and have adopted a HFLC diet cutting out gluten and milk. I drink Puerh black tea too. I am amazed at the difference this has made to my life, I am so full of energy and zest for life once more. My HBAC1 came back with normal blood glucose results, so Type 2 appears to be history too. An added bonus is 12lbs of that horrible, unshiftable weight has melted away in just 3 weeks. I realise that is a bit quick, but it is like some blockage has been released and I am functioning as I should have been for the last 15 years. It's probably "water weight" but boy does it feel good. Thanks for the good advice on the forum, it's been invaluable in getting Dr on board.
