Quick answers

What is Undo?
A mango-flavored, organic hangover strip. Dissolve one on your tongue before bed after a night out — wake up feeling like you didn't.

How do I use it?
Place one strip on your tongue after your last drink, before sleep. Let it dissolve — no water needed.

Is it really organic?
Yes — made with organic ingredients and natural mango flavor. No artificial junk.

When will my order ship?
Orders process in 1–3 business days. You'll get a tracking email as soon as it's on the way.
