Hello
@Forgetfuldan ,
I'm sorry to hear of your troubles, and you're not exactly getting much help, eh? For a T2, exercise, if you can do it, could be a nice walk. If you do something actually strenuous, your liver can kick into gear and start dumping glucose, upping your blood sugars. A walk however, preferably a long, relaxing one, can bring your blood sugars down and won't up your blood pressure. So that is, hopefully, the exercise bit sorted for you.
Now, as for the rest. You mention changing your diet, but not HOW you've changed your diet. The conventional low fat, high carb thing doesn't work for people with a metabolic disorder like ours, after all. Practically all carbs turn to glucose once ingested, so that would include not only straight refined sugars, but also fruit, bread (or anything made with flour, really), rice, pasta, cereal, potatoes. Anything starchy will up your blood sugars. So will "natural" sugars like dates and honey, fructose... All not good.
So now what? Well, if you don't have one yet, get yourself a meter. (
@Rachox has some excellent information on those, so I'm tagging her in). You can't wait for a doc's appointment all the way in February if you're this miserable. I'm a migraineur myself and I know daily ones just won't do, as one can't function when having those. Metformin gave me other side effects, but when I changed my diet to low carb/high fat, I could ditch all diabetes medication with my doc's blessing. I've been in the normal, non-diabetic range ever since, and there's no reason you wouldn't be able to do the same. So...

You're aiming for a rise of no more than 2.0 mmol/l, anything higher means your body couldn't cope with the carb load of said meal. Go that route and you won't be on Met much longer. Also, metformin doesn't actually do anything about the food you ingest... It only tells your liver to knock it off with the glucose dumping in the morning, reducing output by about 75%. It won't do anything about a sandwich or a spud. So... If you ask me, not a pill worth the agony you're in now, and a diet change to get rid of it ASAP seems like a good idea.
Good luck!
Jo
