I have fluttering, twitchy eyelids too. I also have a slight tremor around my mouth . Coenzyme Q helps relieve muscle spasms . Choline also helps . Mercury can cause these spasms but another common cause is the use of antidepressants and other psychiatric drugs . These drugs damage , actually destroy, axons and dendrites in the neuron.They also cause muscle tension and chronic pain that persists years after you stop taking them .
