I Have Extreme Body Spasms Like Just A Few Moments

I have extreme body spasms like just a few moments ago my head was jerking back and forth uncontrollably. They aren't mild but actually quite severe there are times when this happens that I knock things over because my arm will suddenly shoot out and hit things. I can't drive when it gets this bad because my leg will randomly twitch really hard pushing down on whatever pedal I have my foot on. Today it had been much worse every time I lay down multiple parts of my body will do this. I have been having an extremely difficult time staying awake which is unexpected.
