Hi Patriciaian
you have gotten over the worst bit it seems, metformin has that effect on a lot of people from what i have read here, and my own experiences,
when i first started metformin, and each time i have had to up the dosage, its had the same effect on me, I know that i am probably at the limit of what i can take with metformin, ( 2 x 850 per day) and if i take one but then get a delay before eating anything it usually does come back and bite me,
If you have the time and can stand the cost of testing strips then testing will be beneficial, especialy while you are still learning about how to deal with your diabetes,
I used to test often, but now i find i have things under pretty good control, and that my A1c is coming down steadily, i found that even a little increase in exercise makes the best difference !
good luck and keep on checking back here for hints, tips and support from some wonderfull people
best regards
Crofty
