When it rains it pours. my upper left eyelid started twitching last night. woke up this morning & it started again. it goes nonstop, stop for a few seconds or minutes then return. ironically have eye doc appt next week. can i do anything now to stop?

Most likely this is orbital myokymia, a rather benign, but irritating, self-limited and transient condition. Can be associated with eye strain, insomnia, electrolyte imbalance, fatigue, stress, etc., amongst a number of other triggers. Your eye appointment is likely to be more informative and an intervention may be forthcoming.

Most eyelid twitching (fasiculations) are associated with too little sleep, too much caffeine and dry eyes. Try sleeping more, drinking less caffeine and using artificial tears. If it doesn't resolve, then a further work up may be warranted.
