Not ruling out anxiety. But thinking maybe Chronic Fatigue? Not sure if you could look up the symptoms of that anywhere. They are a bit similar. Did read somewhere that calcium, for about 3 or 4 days, can stop the twitching. No idea if this is true or not. As it is not a problem I have myself. Others might have better knowledge on this matter. I am just the first to see it. So wait a few hours and you might get better answers.
You can definitely get twitching from anxiety but you can also get it from a lot of caffeine. One of the main recommendations for people with anxiety is NO CAFFEINE period. Once you're totally off of it, if you still get the twitching and stuff, that can certainly be anxiety. However, I'd follow-up with your physician to check you out just in case there are other issues that are causing it.
I am simply suggesting based on symptoms of anxiety that I get.
Thanks for your response! What symptoms do you get? I have noticed in the past week with no caffeine the twitching tapers and with a Xanax, I don't notice it much at all. Is that common? If you have muscle twitching would Xanax help with this?
