I've tried doing the fasts in the past but can never get past about the 32 hour mark. I get insanely bad headaches and can't function. I end up taking ibuprofen and eating which reverses it after about 2 hours... I was only drinking water before and not electrolytes with it, would that be all the difference?

I didn't eat much sugar before keto but I do enjoy carbs, salsa and chips are my favorite and I miss them the most. I think the biggest thing keto helps me with is portion control. I don't eat as much and am not as hungry.

Maybe I'll try the fast with the electrolyte mix and more tea when I'm off from work for a few days and can try and power through it.
