Hello
@Jokeav
Welcome to the forum, there is a great deal of knowledge and experience here and I hope we will be able to help you.
Although I have taken metformin for some time, I don't know about the other tablets that you mention, but others in the forum may be able to help with this.
In terms of controlling your diabetes, there are several eating solutions available and you need to find the one that suites you best. It is important though to ensure that it is something sustainable that you can continue for the long term.
Many of us on the forum find that following a low carb diet works well.
A good introduction to this is
Maggie Davey's letter which shows how this lady changed her eating style.
It will help if you can find out which foods cause your blood sugars to rise, and eventually arrive at a lists that lets you maintain good blood sugar levels, that you enjoy eating, and fits your lifestyle in terms of how much preparation and cooking you like and have time to do.
A glucose monitor is a way to find this out, by testing before and 2 hours after eating. Also if you can keep a tally of the total number of carbs eaten in a day, your morning reading will guide you on working out how much you need to adjust.
test-review-adjust gives more information on this.
It is all trial and error, so try to be patient, you are aiming for the long term, and a diet that you can sustain.
Best wishes
