newly diagnosed and jumped gun on dosage

Metformin won't do much to reduce your numbers, but cutting right down on carbohydrates in your diet will. (Carbohydrates: bread, pasta, cereals, potato, flour products and anything sugary, including fruit juice and many fruits). My husband started out with a finger tip, spot reading of 24mmol/l and was down to non-diabetic numbers within 9 days. He continued to take Metformin for another 4 months. Almost two years after diagnosis, he continues to have non-diabetic numbers and no meds.
If you are not familiar as yet with the Low Carb High Fat diet (LCHF), do ask, there's loads of information on this site and others and, for many, it is THE way forward to a healthy life.

Hi and welcome. I'm assuming also that you have the standard Metformin and not the Slow Release (SR) version whcih should not be cut. Yes Metformin never has a dramatic effect on blood sugar but helps most if you are overweight. A low-carb diet is the key and if you are not already doing that, it may be possible to come off the tablets if you are lucky.

Shouldn't be a problem as a one off . I started on 3 a day then cut it down to 2 now he has put it upto 4 , I think metformin is used more for loosing a few pounds

Hi!

You'll not have done yourself any harm... Different people react differently to various metformin doses: I was started off on 3x500 metformin a day, and told to cut down if I had any issues. I think in the first month I only ever had the "runs" (literally!) on two or three occasions and they were actually associated with eating higher quantities of carbs (this was pre my current LCHF diet) rather than just the metformin itself. I had no other issues until they changed the brand, which disagreed with me.
