Best instant pick me up?

Heavy period overnight. Head buzzing lightness this morning. Dragging myself around. Usually I eat a banana for some quick energy. Feels like I need a mars bar to tackle this. Anything better?
Internet giving long term solutions.

Dark chocolate
Tea
Porridge

Chicken soup for me. It gives me a burst of energy, no idea why.

Don't think i have time for porridge but the rest sounds good thanks.

I'm vegetarian AtLast (except for sneaky bacon).

I'd see frogs in my back garden.
How often do you see a frog, rabbit or other wildlife in your garden? And does this interest you?

Have you checked if you're anaemic? Might be worthwhile seeing your GP.
I get all that and I am.
For me short term fixes are caffeine, dark chocolate and sometime sugary cereal. Obviously fruit is better but it doesn't give me that same fix (and I only have it every now and again).
