Any Type I people out there taking Metformin on a daily basis? With my endo's approval, I started taking it back in January. 1500 mg 2Xday of the extended release variety. I wanted to try it because I read some encouraging research suggesting that it could be beneficial for Type I diabetics as well as for, of course, Type II.

I wanted to try it for 2 reasons: I wanted to see if it would positively affect my insulin sensitivity and I wanted to see if, over an extended period of time, it would do anything to my weight. After 7 months of being on it, I can say that I have seen some benefit, albeit rather small. My insulin sensitivity has increased a little bit - not as great as I might have thought however. I'm taking, on average, about 10-15 units less insulin each day than I was before. I have also lost about 10-15 pounds. I can't attribute the weight loss specifically to the Metformin, but I think because I am taking less insulin daily it has facilitated my body's ability to burn fat and not hold onto it.

After 4 months of being on it, my A1c dropped ever so slightly from 6.5 to 6.2. If anything, I think the Metformin smooths out my glucose profile just a little bit. I don't experience the sharp spikes in glucose as much and, when I do get too high, my bs comes back down a little faster. For example, if I get up to 250 due to an incorrect insulin/carb bolus calc, it might come back into normal range in 2 hours instead of 3 or 4. My correction boluses also seem to be less.

Anyway, it's been an interesting personal experiment. I'll throw in my disclaimer at this point and remind everyone that this is just my experience and may not apply to anyone else's experience.

So, with that said, anyone care to discuss?

Hi there, well in December they tried Metformin on me as a T1 within 12 hours I went from normal BGs to over 200 and by the second day I was at 300. The Endo placed me back on insulin. I am still on a low dosage of insulin, (I think) I am now at 14units of Lantus at bedtime and sliding scale of novolog for premeal correction. Usually don't take more than 5 units per DAY, sometimes I don't take any at all. I am trying to work on A1c which was 6.6 early Dec., but my numbers are everywhere these days. I am trying to figure this out AGAIN, sometimes it's frustrating. Good luck!
