If you drink a gallon of distilled water all at once, it could screw up electrolyte balance.

No it won't.

You get most of your minerals from your food, not your water. Distilled water has zero health effects.

My daughter just told me, "If you really stretch it, you can make what you post on social media true."

Alas, I must concede the point: upon actual cursory research, drinking distilled water is NOT a health risk.

(I was once admitted to hospital because of crazy electrolyte levels, while presenting other symptoms as well. Is long story. Perhaps it's time for me to stop worrying about potassium...)
