Hi my husband was diagnosed with type 2 about a month ago and put on 1 metaformin twice a day, his sugars still jumped from 4 to 18 but i have put him on a very low carb diet (trying to stay below 20g a day) and they seem to have been staying between 6 and 7 for 3 days now and would like to know if he can stop taking the tablets as worried he might dip too low in the evening. Any advice
