Jitters...Serious Jitters

I have had serious jitters recently and I am not sure why.  It's almost like my body is pissed that I am sitting down.  I could pace all night and still not wear through all of the nervous energy.  It's played havoc on my sleep .  I get the jitters so bad when I am trying to fall asleep that I have to sleep on the couch - it drives my wife nuts and I don't blame her.  It's driving me nuts.

What makes it even worse:  I can't get my brain to shut down after being jolted awake by my body.  So I stay up for a good portion of the night after I wake up.  Woo.  I am so frickin' tired right now, it's ridiculous.  I have doctors' appointments coming out of my ears for the next few weeks.  When is this all going to end?

I feel like someone is at the wheel today and It's not a fun feeling.  I hate feeling this way, but how do I stop it?  I am hoping that the sleep testing actually has some effect and resolves some of these ridiculous sleep issues.  Is this the way it's going to be?  PTSD wearing my body down to the point that I get sick all the time and it starts to break down.

Of course, all of this uncertainty just makes the nerves and the jitters worse.  I won't live like this.  There has got to be some way of fixing this or at least mitigating the effects of all of this on my body.  If anyone has any sage advice, I'm all ears!!
