I was diagnosed with osteopenia when I was in my early 50s and I take the once a week Fosamax (Alendronic acid). I'm not sure why people are saying it's "tedious" though. I've gotten into the habit of taking it Saturday mornings as soon as I get up. So it's pretty easy to stay upright then, and delay having breakfast for about 30 minutes. I never have breakfast as soon as I get up anyway. By the time I've made the bed, washed my face, been to the loo, and gotten dressed there's probably 15-20 minutes just there. Most days I will also be going for a walk as well, so it's probably more like an hour before I eat anything.
I would certainly stick with the med limpy because I took it initially for a few years and there was a definite improvement, and then I stopped taking it for another couple of years, and that certainly showed as well. I've been back on it for about 18 months now and I'm due to have my next BMD in June, so I certainly hope to see an improvement. My father had osteoporosis so it's something that really scares me because I saw what happened to him.
