Hi Meghom, just going back to your post about the Budwig mixture, I honestly think this diet is a load of rubbish. I Googled Budwig as you suggest and found websites that tick all the boxes for dodgy science, such as talking about a 'cure for cancer' and a 'cure for type 2 diabetes' and stating that conventional doctors know nothing about these conditions.
If your partner's blood glucose went down after two days on this breakfast it could be because it is composed of fat and protein rather than carbohydrates, or there could be many other coincidental reasons. If the Metformin isn't working for your partner the best thing he can do is go back to his doctor and ask about a change in medication and/or further diet advice.
This is just my opinion of course and I don't mean to criticise you for wanting to do the best for the partner, but I strongly believe this flaxseed oil/cottage cheese mixture is not it.
