This is almost a typical picture of anxiety...if you go through the archives of this forum you will see this described over and over. It is still good to see a neurologist to be sure and rule out any remote possibilty of a neurological origin but it does not sound organic to me.
I have gone through the same thing last spring..and still haven't fully recovered..BUT.. One advice I can give you is:
Do NOT wait and hope the symptoms will go away. What you need to do is go see a neurologist. Ask for EMG test, even if he says you're ok. Trust me, it's worth the money. But do it quick. Do not wait 3-4 weeks with basically no sleep at all.
"For 4 days I could never reach deep sleep, just fall asleep enough to dream then wake about every 30-40 minutes"
I had the same thing and I know what it does to your body. Tingling, twitching..
Anxiety and stress can do lot of harm to your mind & body.
It really is a vicious circle: you get these physical symptoms from anxiety..and having physical symptoms makes the anxiety worse and there you are...
1) Go through every necessary test to make you convinced you do not have some serious disease (ALS, Parkinsons etc..)
2) Leave Google alone.. Don't try "ALS SYMPTOMS" or anything like that..Trust me, I know what I'm talking about.. ;-)
3) Try to do some exercise every day, maybe 30 minutes of walking/jogging. It really makes a difference once you realize "Wait a minute, ALS patient can not do this.."
It sounds like benign fasciculation syndrome. Did you get a rash? You should see a neurologist and stop taking all those drugs. The neurologist will probably be a waste of time and money but it will atleast give you peace of mind that you don't have a tumor, CJD, or ALS.
It's not "stress" or "anxiety."
