benign essential trem
"I have had a mild case of benign essential tremor for almost 12 years.  My primary care doctor has always associated my shaking with anxiety or hormones, however my neurologist diagnosed it as benign essential tremor.  I have been taking Primidone (only 50mg twice a day) for a month now and it seems to have decreased the shaking a bit.  However, it makes me extremely tired and I sometimes have an odd dizzy feeling the first hour or so after taking it.  I am unsure if it will go away completely, but it definitely has helped so I will continue to take this medication to see if the side effects eventually go away."
