"Cutting back on carbs" sounds good, and can only help...but is a bit vague. What kind of carbs are you eating/how many grams on average per day? It wasn't until completely cutting out bread, cereal, spuds (n chips), pasta and rice that I really started to get things under control. I generally eat less than 50g carbs a day along with at least 2 litres of fluid and my blood sugar levels (without medication) is mainly under 7.5mmols now, often down below 6mmols. I'd say try being even more strict with carbs first before meds...see if you can handle it...but, to be fair, many people cope well on metformin - I am already on lots of meds for other stuff, so the less the better.
