Oh my god! Wow! I have had this for at least six years that I know!!! I started twitching in March 2001 and have been twitching ever since! I woke up one morning and my body was twitching like the lights on a christmas tree! Around this time, I also started noticing that noise. eeeeiiiiiiiiirrrrrrr, yes I know - every time I swallowed - thought it was bulbar onset too!!! In addition to the neurological tests, I had a endoscopy and it was reflux, another condition brought on by stress sometimes. With the whole bulbar thing back SIX YEARS AGO!!!, I would read signs out loud on the way home in my car from work and try to say them fast to see if I was stuttering or slurring my speech, or I stared at my tongue for hours in the mirror to see if it twitched. I was in bad shape with the checking. Six years later, still twitching, more during stressful situations, less at other times. I don't worry about it any longer though.
