My right eye twitched every day for 3 months last year and then went away. it started twitching this time again 3 months and i feel slight twitches in my lips now too. i've used eye drops and vitamin b-12, cut back on caffeine, but nothing helps?

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor, preferably a neurologist. Wish you good health!

You may have orbital myokymia which usually is benign and self-limited and associated with fatigue, eye strain, stress, etc. But the persistence over 3 months is unusual and now you are noting lip involvement. Potentially, therefore, this could be facial myokymia, and if so, this does need investigation. Perhaps a neurologist can examine this and provide some therapeutic intervention.
