@mikaylar I had to take a look at your bio...seems you've a long list of issues. And now you state your two major issues -- headache and dizziness -- that has your life move between bed and couch, for over six years. All this surfaced as u asked a simple question about dessert desire, which I could've answered more simply -- like others here -- that while I do like one muffin (or its equivalent) a day, End of story.
But I also said I am mostly busy enjoying my time in pursuits that I believe I'd feel terrible on my last day if I did not use my time as I do. I call it finding one's purpose. Our Healthy lifestyle follows Because we want to be most productive. Purpose is supreme in human's life; without it we lose the luster that life bestows us. And I am not alone in this thinking.

You are waiting for doctors to come with an answer for your condition. I rarely see my doctor even though healthcare is free here. Nor do I use any meds, or did any tests tho cud use cataract surgery in one eye. Some infirmities as an 82 y.o. but still quite independent living. Did my health Result From my outlook? I believe so.

U say u r prediabetic. I belong to this group in my country to share my knowledge tho I have no signs. The website also says one can bring down blood sugar levels to normal within an hour of exercise. But obviously it's no use for you.

But since you say your condition started some six years ago, can you not trace what might have pushed you into this and thus reclaim whatever YOU can? I say this because doctors have a limit -- there are spaces where the patient has much control. That's how I run my life. That's what I might be able to offer. Maybe I went too deep. Regardless I wish you luck.
