You know it's the Bonk when...

Peanut butter and honey sandwich is my emergency food now. It always feels so comforting after gels, electrolytes and other space food...

I've given up eating gels as emergency food - they only ever make me feel sick. Work well if ingested when not under stress though

The reason they don't always work well as an 'emergency food' is if you only ever take them in that situation you're not used to them and your body might reject them.

Train yourself to eat something and you will be much more effective at using it.
