Hello, I am curious as to whether or not anyone else has experienced this while in the trial. During the two week open label phase I had no side-effects other than a little bit of dizziness but this seemed to get less as time went on. During the two week open label I tripped and fell down some stairs. I partially tore my rotator cuff and got a lot of bruises. Actually everyone one was surprised how soon I was up and going again. I have since been started in the randomization phase. I recently had to stop taking the trial drug for 48 hours. I was impulsive, disinhibited and just generally let's say care free. But even more exciting I had regained most of my muscle strength and didn't feel stiff or tired. Physically I had significant improvement and everyone says I am much happier but close friends and relatives are worried at how fast I am talking sometimes and that I am going to over due it. I am basically physically doing everything I could pre-diagnosis of ALS. When I think back to the two week open label phase I can now see that I was feeling this same way after taking the trial drug for about four days. So good in fact I was feeling overly confident which led to my fall. I was only slowed down for about two days with the fall? I am curious to hear what others have experienced thus far?
