“Okay, so I’ve been using Flowever’s Sleep Flow for about a month now, and the first thing I noticed? Waking up with way more energy. Like, actually getting up and feeling good instead of hitting snooze five times. Then a couple weeks in, my mood got so much better too. Didn’t see that one coming, but I’m totally here for it!”
Rafael R. Verified Buyer

FAQ

before you grab the deal

When does Black November end?

Monday, November 30 at 11:59 PM ET. After that, Sleep Flow goes back to $49 a bottle.

Do I need a discount code?

No. Sale prices are applied automatically when you add Sleep Flow to your cart.

Is it the same Sleep Flow?

Yes. Same formula, same 60 mL bottle, same 30 nights per bottle. Only the price is different.

Does the money-back guarantee cover sale orders?

Yes. Every order is covered by our 30-day money-back guarantee. Email hello@flowever.us within 30 days, with no need to send the product back. Refunds go to your original payment method, usually within 5–7 business days.

Does Sleep Flow contain melatonin?

No added melatonin. Tart cherry naturally contains tiny amounts, but the formula relies on L-theanine, chamomile and calming botanicals to help you wind down.

Is it habit-forming? Is it a sleeping pill?

No. Sleep Flow contains no habit-forming sleep medications or conventional sedatives. It is a dietary supplement, not a pharmaceutical sleep medication.

How do I take it, and how soon will I notice a difference?

Take 2 full droppers (2 mL) straight into your mouth before bed. Responses vary: some people notice a difference in the first nights, others find it works best as part of a consistent routine over a couple of weeks.

Can I take it every night, or with other medication?

Sleep Flow is designed for nightly use, with no need to cycle off. If you take melatonin, prescription sleep medication or any other medication, are pregnant or breastfeeding, or have a medical condition, talk to your doctor before starting.
