after reading the marginal effect metformin has on bs levels there is no rush I suppose
viv and grazer are right that probably at the moment it will make no real difference to your BG levels but don't underestimate the usefulness of Metformin. I was diagnosed 8 weeks ago and am low carbing at roughly 50 to 60g of carbs a day and take 2 x Metformin each day with no side effects. My BS levels are now back in the 4.5 to 6.5 range at all times and started in the 20's
Metformin may only reduce your "background" BS levels by around 1 mmol/l but with me I noticed a definite improvement with the BS spikes you get after eating. The effect happened within a couple of days after starting to take it. That is pretty useful as the extra tiny bit of latitude it gives you in what you can eat at anyone mealtime is really good.
If you low carb at whatever level you find suits you and then get control of your levels then pretty soon you'll be worrying about the gp taking it away like many of us do!
I also thoroughly recommend sids recommendation (in the other thread) that you test with a blood sugar meter. I test before and then 2 hours after every meal. If you have a long gap between when you wake up and have breakfast test when you wake up as well. Keeps me on the straight and narrow and importantly will tell you what you can and can't eat.
