I've had this twitch in my lower right eyelid for a year. It usually stops for a week or so then slowly comes back in bursts. pretty soon it just twitches all day. I used to think it had something to do with my sleeping patterns but i've been getting 8 hours of sleep everyday for the past few months and nothing. Also i used to smoke pot and thought that it was causing it but after not smoking for 2 months i'm worried. What could it possibly be? Are there any cases where it just stayed permanently?? I am very worried and it has caused much stress. Any educated feedback would be much appreciated/
