I am due for major knee surgery next week but both my knees are so weak that they let me fall often. When I am just sitting being quiet they shake (kinda looks like grand mal seizure - but only my legs shake not my whole body) I had epilepsy for 25, but been 26 seizure free - so I call these anxiety attacks - the only medicine that works is klonopin, but getting a doctor to prescribe it has been a challenge. I only take it when the anxiety attack happens....why is it so hard to get a pill that works instantly in 10-15 to solve a problem
