Anxiety-related muscle twitches. Does anyone get them?

[Rafterman]

Hey all,
I am not taking about cramps, but instead those little high-speed twitches that one may sometime get on their eyelid when stressed. Does anyone here get them anywhere else? My wife suffers from these on her quads and upper arms, and she is about to jump off the roof because they can sometimes indicate serious disease. Technically known as "fasciculation's", some people get them from working out too hard, stress, or tapering off any psychoactive med. Some other's experience them when on an ATD. None of those apply to my wife right now. I have suffered from them for quite a while now, but I do have motor-neuron disease and that is what is freaking her out. She is afraid that she might have it, too. I told her to stop worrying. Those group of diseases are classified as "extremely rare", affecting 1 person in every 50,000. I got mine through excessive exposure to environmental toxin's. She has never been exposed to anything like that. With her, it is probably a case of benign fasciculation  syndrome...which is a well recognized phenomenon affecting those in the medical field. She has tried increasing and decreasing her magnesium, calcium, potassium and b-12 intake. Nothing slows them down. In any event, stopping them is secondary. Her primary worry is with regard to what made them start in the first place.
SO, I promised her that I would post on here to see if anyone is suffering from them, and any further details that that person would care to share. Thanks for reading.  Peace.  RM

YES i get this especially after i have forgotten to take my SSNRI or have not had D!@Z£P@m for a good few days its usually as i go to sleep and accompanied by a brain zaps its mainly my right bicep causing my arm to bend really fast and shocking me awake. I'm convinced that its just the meds  it will happen say a few times and then i'll realise that i've missed one or two of my meds out take it and it calms down. It is mainly my SSNRI abstinence that does it.
This has only started happeninig since a few months after changing from an SSRI to a SSNRI and sometimes just happens without having missed anything out of my daily meds.
Hope this helps in someway possible even if its just knowing someone else has relatively similar eperiences.

Thanks Blandy,
It really helps and I appreciate you letting me know about it. The more real life examples that I can tell my wife about, the better. The odd thing is that she never had them when on her SSRI's and SSNRI's, but has them now, when she isn't on anything. They say that 99% of the time that do occur, they occur in healthy people. She is just on edge because when I got them it turned out that the were a symptom of a disease. I think that as time goes by and she realizes that she is still okay, her nerves will settle. Thanks a lot for contributing your story!  RM
