Metformin causing nausea and gagging?

Did metformin make any one else gag when they tried to up their doses? Originally, I had to take one with breakfast and add one each week, but once I got to one with breakfast and one with dinner. But after two days of that, I had half a chipotle bowl and a couple of cookies and I was gagging. I was also nauseous for the rest of the night and into the next morning.
