Oh, Albert, my heart is truly breaking for you. Fortunately, when I went through my really bad ALS scare, I was still a college student and had already dropped out of school, so I had nothing but time on my hands to worry. I was prescribed 1mg of klonopin and it was as if I had taken some super powerful opiate. I was basically knocked unconscious the first time I took it. Luckily, I soon saw a psychiatrist after that and she cut my dose in half, so it helped with the anxiety without incapacitating me. I missed at least two days of work a couple of years ago because I was CERTAIN I had colon cancer. I spent two years with that fear, until a colonoscopy two weeks ago dispelled it forever. But you MUST find some way to get back to work. I am at work right now. I am not doing my job. Instead I am on an anxiety board posting about my fears of neurological disease, but I am physically present. Is that possible for you? Can you at least be at your desk or whatever, even if your mind isn't present, so that you don't get fired? I sincerely doubt you have ALS, especially after just one incident of slurred speech while you were tired. We all slur our speech from time to time. I know I do. Good luck, my friend.
