hi Niki - I'm not sure if that is too much for you? the best way to find out is keep testing using your glucometer. The maximum dosage of Metformin daily is 3000mg I was told by my endo and GP... they wouldn't put me on more than that when I was on it. I don't know if docs in other places use a higher dosage? But I'm thinking if you've only taken 2000mg you should be Ok. What was the timeframe between each tablet? Usually anything over 6-8 hours is Ok for most drugs. If you're not sure though it's a good idea to discuss this with your docs. They are the best people to advise you how to take your medication. A pharmacist may also be able to offer some advice too. Make sure you keep quick acting carbs close at hand just in case too (yes, I did have some hypos on Metformin which I know some people haven't experienced). Let us know how you go.
