My wife has Type 2 diabetes and has been taking Metformin for sometime. She was getting very tired, lethargic even after a very long sleep. We put it down to her diabetes.
It was only when looking into my own problems that we noticed the link with B-12 and metformin. After a few weeks taking B-12 supplements she is so much better. She had mentioned the tiredness to the family doctor and diabetic practitioner but they had never thought of mentioning it to her - grrr!
