Surprisingly good
I did the 3-day cleanse, and while the drink was surprisingly delicious (thick, sweet, flavorful) it definitely wasn't enough to keep me from feeling hungry and crave solid food. Let's be real: it's ~5 oz of fluid PER DAY for 3 days and nothing else (besides water & non-caffeinated tea), so to think you'll feel 100% satiated is probably an unrealistic expectation.
I didn't experience any changes in bowel movements during the 3 days, but the break from solid food did seem to help my guts "reset" and helped with constipation starting on day 4.
Overall I'd recommend this product and plan on doing it regularly moving forward as a supplement to my regular eating regimen.
