Had a bit of a late lunch today, and okay, I hadn't had breakfast other than a few biscuits and a cup of tea, but for lunch I had scrambled egg on toast, 2 eggs, lots of butter, 2 slices of toast and milk in the egg as well, and I still felt hungry and shaky afterwards. I ate some more biscuits in case it was to do with my blood sugar levels and helped a little bit, but then I was/am still a bit shakey or "buzzy".
What causes this and how can I avoid it?
