@CSKSCS I'm afraid I don't understand your problems over letting people know - assuming that they are people you might like or need to know. Type 2 diabetes, in the plain ordinary form is being unable to deal with carbohydrate - the starch and sugar in our diet.
If you are one of the many Humans unable to cope with the sorts of foods supermarkets want to sell you in order to turn a good profit, it is perhaps unfortunate, or bad luck but it is just that, nothing more.
There are no carbs in diet coke or any diet drink - though they can make the bladder a bit more excitable than usual - at least it seems that way for me, so in hot weather I drink plain water or various teas, camomile, mint or liquorice.
By swapping to lower carb foods many people find that their metabolism heaves a sigh or relief and goes back to normal - in the months after diagnosis I saw my blood glucose levels normalise, and then my clothes started sliding off due to losing weight which was entirely effortless and unplanned - all I did was find out what I could eat without causing elevated levels.
Although lose weight is often cited as how to reverse type 2 I found that reversing type 2 caused weightloss - I lost over 12 inches from my waist (I was almost spherical) when all the advice on eating low fat and high carb had never been the slightest use.
