I'm worried because my bottom eyelid has been twitching for almost a month now, any clue why, what do you suggest?

Benign but annoying: Eyelid fasciculation or twitching is usually from fatigue, stress or even low serum potassium levels. Eating healthy and obtaining the proper amount of sleep is a good start. There is no easy answer for stress related side effects except to become mentally disciplined to resist stress. Look at it this way, your body has a barometer or gauge to help warn when to relax.
