"took this medication to help with weigh loss. it did help with weight loss, but i never felt well. this impacted my ability to exercise, which really decreased my weight loss. then four months in, i got very ill with a bladder infection that did not clear up. lots of lower back pain, front pain (where gallbladder is located, but i do not have mine) and continued lack of energy. i mention to my weight loss doctor and am informed that this medication can cause kidney stones. so, i am off this medication and in the process of ruling out what is wrong with me- but most likely kidney stones caused by qysmia. the pain and doctor bills were not worth the 10 pound weight loss. i would avoid it."
