Eyelid Drooping Comes and Goes?

I recently started a new job that is very intense. My sister noticed my eye was drooping the other night. I brushed it off as stress. About 5 weeks later, I went on a trip to Mexico and it happened again but this time with blurry vision. Fast forward to this Saturday morning - it happened again but drooped really bad and kind of now does it intermittently. My only other symptoms are blurry vision and occasional tingling. I am not really sure what to do. I went to my doctor scheduled an appointment with an optometrist and neurologist but not till July. Happens at random times and goes back to normal. Not asking for medical advice just want to see if there is anyone else that had this issue.
