Hello dmhobbit: The Skeezyks doesn't really know anything about this. I do have sort-of a tremor that I experience 24 / 7 throughout my body. It's come on within the last couple of years or so I would say. It's not so significant that anyone else would notice. But I feel it. I haven't sought any treatment for it.
Are you familiar with PsychCentral's sister website: NeuroTalk? There are a lot of members there who have lots of experience with these sorts of things. You might find it useful to check it out:
