I've drunk Besunyen, and I've had diarrhea, and I've also drunk Herbalife Meal Replacement Milkshake. It's too painful to use this meal replacement, and it's really not as delicious as rice. I drank three cans, spent 1111 yuan, and lost five pounds, but I didn't lose my weight. Later, I changed to herbal slimming powder, which was one kilogram every two days. This effect was good! Drink Besunyen when you are constipated.
