What i have heard from other members that you can get Metoformin XR from your doctor which is slow release and can be better.
Think normal Metoformin is more effective.
I have been diagnosed T2 5 weeks last friday so i am a learner.
From what i hear its better to carry on taking it and it will eventually get beter after 5 weeks to 3 months.
Heard of someone going on insulin as stomach cramps were that bad.
I am unemployed soi grin and bear it, ok now.
After a week the Metoformin did get my bllood glucose down from 16 to around 7 - 8 mm/l.
All the best.
Davey.
