Hi and welcome to the forum, the fasting test isn't the horror experience we all think it is. From early years, our parents programmed us to eat three square meals, meat and two veg with a Sunday roast, fish and chips on a payday, cereals for breakfast as a healthy diet!
Well, we're different, and have learned that having RH must be approached from a quite different lifestyle choice.
Sometimes because of the symptoms, we tend to forget that we do have some good days and some bad days, the brain fog is part of the bad, you didn't sleep well enough, your food intake of carbs wasn't low enough to stop the insulin overshoot. But getting days without a hypo, is brilliant, seeing that you were only diagnosed a few months ago.
Your normal hba1c and fasting levels is were you want to be and because of the low carb diet, you will lose weight.
There is a lot of information on this forum, do read because, there is some great knowledge, that you can learn from.
Any questions please ask, I am interested in how us RH ers got diagnosed because of my long battle with the medical care. So do write a little about your personal experience.
Best wishes
