Anyone take Medicine to increase bone density/ osteoporosis ?

[tabbycat15]

I suffered with Anorexia from aged 13 - 40. I am currently well & see a psychiatrist for treatment of depression. I am at a healthy weight now aged 42 but the last 3 bone density scans I have had have shown my density worsening. I take calcium & vitamin D. My Dr had referred me to a specialist & he had prescribed me Fosamax. I am in Australia do not sure if it's the same in in the UK, does anyone take this medication? What are the side effects like? .

Only calcium and Vit D tablets, for me and my early perimenopausal DD.
