I also have these sensations which I can only describe as nerve cells firing randomly. If I lie completely still (e.g., meditate), I sense a steady stream of low intensity muscle spasms all up and down my arms and legs. Sometimes I would describe it as almost painful. I also suffer from a common condition called RLS (restless legs syndrome) which some researchers claim is related to dopamine levels in the body. The sensations I describe above have a flavor and texture similar to that of an RLS attack. For RLS I take neurontin and klonopin at bedtime. I should experiment to see if these drugs have any effect on the random firings. BTW: I am on 10mg Eldepry and 2 mg Akineton.
