I'd definitely recommend it to anyone needing a boost in their weight loss journey!"

"I want to caution others—after taking this product without my usual morning coffee, I experienced fatigue, brain fog, and a racing heartbeat.

I have not noticed any weight loss so far."

"Flyby is truly a lifesaver! During a long girls' weekend with a lot of wine, I felt great every morning. As long as I followed the instructions and took the recommended capsules, I woke up refreshed and ready to go. I plan to keep these on hand for any weekend with drinks."
