Personally, I'm always very wary of anything that offers a "quick fix" for diabetes (or anything else for that matter!).
Plenty of people on here (myself included) have got their T2 under control but it takes time, hard work and dedication
I've got my HbA1c down to non-diabetic levels in 3 months by strictly controlling the amount of carbs I eat (< 20g a day), but I would in no way consider myself "cured" because my body still can't process carbs properly (so I still have diabetes)
The best advice I can give is accept you have diabetes and accept it's probably for life. Once you've done that, you need to start working out the best way of managing it and keeping it under control. For some (including myself), that way was LCHF but that's far from the only way and you need to get a meter so you are making informed decisions about what does and doesn't affect your BS levels.
Good luck
