Hi @me1229, It was for me. I was having back pain and stomach pain, particularly on the right, extreme fatigue - along with a variety of other symptoms. After a whole day they chalked it up to metformin and told me to get off of it, which concerned me, as it fights cancer, but I know there are other alternatives. My other half is healthy as a horse. He rarely ever gets more than a cold or the occasional flu. Is your husband alright?
