nausea/vomiting
"I was in the hospital for 11 days, diagnosed with failing kidneys which made me highly nauseated.  I've lost 20 lbs. in 2 months.  The shots worked quicker for me than the 4mg pills I'm taking at home.  But reading through the posts, I now know why I was severely constipated, and I normally suffer from Irritable Bowel Syndrome....constant diarrhea.  My kidneys continue to deteriorate which causes the nausea.  As far as the person who mentioned they stopped taking it because of a headache...the headache probably came from extreme vomiting or the blood pressure going up from the stress of vomiting.  That's what happened to me.  I would give it another try."
