Fortunately I have been retired for 4 years now. Since then my tremors have escalated, especially in the past two years. I have not had to deal with a computer for a while. I do a ton of texting in light of the fact that I am completely deaf in one ear with declining hearing in the other, so it is difficult for me to hear on the phone. I just slowly put it out there one letter at a time. Sometimes I wonder if my tremors are getting worse simply because I do not have to use my hands like I used to. I have a horrible time writing now. When I was working, I wrote and typed all of the time. In fact, back in those days, my most annoying trait was that my head would bob horribly when I talked on the phone, which was a lot. It was very much noticed by my coworkers. I remember my boss heavily encouraged me to go the doctor to see if I had Parkinsons. That was when I was officially diagnosed with essential tremor about 14 years ago.
This is going to sound crazy, but it works somewhat for me. The only advice I have is to create some type of distraction for yourself. I have found that if I am not as focused on the task that makes me shake, I seem to do better. The more I try to focus on not shaking, the more I shake. It becomes an anxiety sort of thing.
For example, if I am focusing on putting on makeup, I play some type of podcast and try to focus on that instead. If I am texting, I can focus on a television program. If you are typing on a keyboard, try playing some of your favorite music in the background. Try to focus on the tune instead of your hands. Hopefully you can come up with your own distractions, and see if it helps. I hope all of that made sense.
