i took it for 6 weeks, i was feeling sick, like nausea, a shitload of pain in the lower part of my abs, and in my lower back, i was peeing non stop and it ached when i did, smelly urine, i just stopped and within 5 days i was okay, i took blood and urine work and was fine again. My doc said it was a tiny stone taht dissolved with the amount of water i taking. But dont worry, it happened to me but i will not probably happen to u.
