Anyone has essential tremors not caused by Parkinsons, Myasthenia Gravis or medications?

I started having tremors in a hospital while I was almost done with H1N1 and a chronic severe pneumonia. I still get them at different times, sleeping, in a place from a oddor/smell reaction. Just for no reason or for forcing my body when I should rest. I was diagnosed with essential tremors by my neurologist ,and the meaning that they don't know the cause.

Is depressing because you never know when I will have them and how strong. Some are strongers, some are in my legs more than my arms. Some feel like inside my whole body.

To sleep they had to put me on clonopin (klonopin) and during the day that is a mild medication I have to take Ativan if it is needed.

Once in a while I get involuntary movements, but not that often.
