I have taken Didrocal for little over 2 years and I am off it now for a year. I got dizzie spells at first and the the dizziness stayed and I could not figure it out until I started reading about Didrocal on the Healthboard, I also had hairloss, not funny anymore. The dizziness is pretty well gone but I still have buzzing sound in my head. I was put on Actonell but that gave so much joint pain and went off in a hurry.paxton
