Osteoporosis
"By the end of the first day I was very lethargic and had abdominal cramps and bloating, followed by diarrhea. Throughout the night and all through the second day, I experienced flu-like symptoms, relieved slightly with aspirin, but continued with abdominal tenderness and discomfort as well as very lethargic. By the third day, the muscle aches were gone, but the abdominal tenderness continued. Appetite did go down. Hopefully, there is truth to the first dose being the most difficult in regards to side effects."
