NO Metformin = Constipation?

Has anyone been taken off of Metformin and become constipated?

My doctor took me off Metformin about 2 months ago because I'm now able to control my Type 2 with diet and exercise. When I was on Metformin, I had a bowel movement every morning and I had no problem with passing a stool.

As soon as I was off Metformin, I became constipated. My bowel movements became very large and dry, even painful to pass. It's been like this for 2 months now.
