Re: Bulbar ALS?
Twitching on its own is not indicative of ALS.
The temporalis muscle is notoriously prone to twitching because of simple things like jaw tension (you won't even know you have this half the time), or general muscle tension in your face and head. Guess what causes that kind of tension? Anxiety and stress. I would imagine you're experiencing both of those in shovelfuls right now.
You might even be grinding your teeth in your sleep too, or have TMJ, which could also cause ongoing twitches. Even neck tension can cause a domino effect and cause the facial muscles to become overly tense.
Try gently massaging your jaw and face, and use heat on it to relax the muscles. You may not even feel overt tension in your face or neck, so don't panic if you're now thinking "but my face and neck don't feel tense at all, it's DEFINITELY the scary thing". Tension in those areas can actually be quite subtle. Take it from somebody who had chronic eyelid and jaw twitches due to an irritated disc in my neck. I didn't feel the tension at all at the time. But once I started to work on my face and neck, the twitching subsided.
Edit - You could also try taking some magnesium to see if it helps!
