I consider myself to have a very sweet tooth and have frequently for a number of years had dizzy/weak feeling if I have been physically active and went to long without a sweet. When this feeling comes on I feel I must have a large quantity of something sweet and after doing so a few minutes later the feeling passes.
I have been to the doctor about it and have been checked for diabetes but all clear.

Another point I mentioned to the doctor I constantly feel tired but i'm okay if I am active but as soon as I sit down fall asleep,this has been the case for the last few of years. I can sleep easy 10 hrs.

The reason I am asking this is that I have been trying to nearly cut out all chocolate and sweets during the day and wonder if this feelings will clear as I cut down my intake of sweets.
