A friend taught me an interesting way to control tremor. At first I thought it was hokey, but it works for me. I take a deep breath in and say or think "Peace". On the deep exhale I say or think "Quiet hand or Quiet arm". At first I tried this for about a half hour before some results. The second time the tremor stopped after about 10 minutes. The third time took just a couple of minutes and now it just takes 4 or 5 breaths. If the hand keeps trembling, I move a finger about 1/4" and that stops it. This has made going to sleep ever so much easier as I'm not constantly patting myself. My friend explained that it's a form of self-hypnosis. At least it works for me.
