Pre diabetes here.
Bad day today. I over ate on chocolate and carbs. Sharing this to make myself feel guilty and to make myself not do the same thing tomorrow.
I don't know where you are on the spectrum, but if you are pre-diabetic some simple changes might do the trick, such as avoiding sugary things, pasta, rice, too much bread, potatos, and cutting out cereal and reducing the milk at breakfast. If you like fruit, reducing the quantity.
I was never diagnosed pre-diabetic but sometimes wish I had been. Because my diabetes was "full-flown" I had to make much more drastic changes. You too might need to go down that road if you let things go as far as I did. You have a chance to do better than I did.
I wish you the best of persistence and courage in taking some simple steps now that might avoid more drastic stuff later.
