Small jumps symptoms and conditions

As a prime candidate for osteoporosis I was prescribed Fosamax at least 12 years ago if not longer. At the time I started taking it, my mother was very ill and did pass. That was when I noticed small 'jumps' in my legs at night which I attributed to the stress of the time.

Over the years, the 'jumps' increased in intensity to almost convulsive movements of not only my legs - but my arms - head - neck - torso. There were times when I thought I would be flung from my bed or dislocate my joints so strong were the muscle contractions. It was impossible to get to sleep and I was often woken from sleep by a convulsive movement.

I went to the Seattle Sleep Clinic for help (around 2000/01) after 5+ years of progressive worsening of these symptoms. Unfortunately, the doctor only wanted to fit me into the 'restless leg syndrome' in spite of my constant statement that I had NO feeling of 'creepy crawly, etc' before the convulsion. None. They just whipped me about out of the blue. No resolution.

About two months ago I ran out of Fosamax (actually taking a generic here in Mexico) and (for whatever reason) I did not refill. Since then I have noticed a HUGE lessening in these god-awful, annoying, scary convulsive movements. I have made no other changes in medications nor can I think of anything else that would cause this reprieve. A "milagro" isn't likely.

I haven't seen this side affect listed and am wondering if any other people have experienced this 'convulsive' problem?
