I know this is kind of long, but I think it's worth your time to at least skim it.
You should get that stuff checked out. Let me share my story with you.
I was on numerous atypical antipsychotics (risperdal, seroquel, zyprexa, abilify, geodon) and vistaril at various times during the past two years. All gave me terrible reactions. I stopped taking Seroquel after about four days because I noticed that after I took it I experienced the symptoms you describe so severely that I was unable to sleep at night, and feared that I was dying. Nearly went to the ER, but just stopped taking the medication instead. The newer antipsychotics have been linked to all kinds of horrendous side effects, including permanent movement disorders and pituitary tumors, which your doctor may not tell you because he may not know.

Trusting your doctor to know about all the side effects of any of these medications is incredibly imprudent. These drugs are still under patent, and their manufacturers are still suppressing information about their dangers in order to make a buck. So your doctor will probably know less about it than the internet--not to mention that no doctor has the time to really thoroughly research every single medication/combination he prescribes.
I personally have a pituitary tumor that may or may not be caused by the medications, but was certainly made worse by them. My doctor didn't know about the tumor risk and didn't see it on my first MRI, which I got after Risperdal caused me to have a grand mal seizure in my sleep in March 2008. Since taking Geodon for four days in late March 2009, I have been having constant headaches, pretty severely, on a daily basis, and panic attacks. The morning panic attacks started when I was using Mirena IUD birth control, and have not ceased. I got Mirena removed in the ER about four and a half months ago, and later got an MRI that revealed a 13mm macroadenoma on my pituitary gland (i.e. a sizeable "non-cancerous" but growing tumor on my brain). Upon examination of the 2008 MRI, my doctors determined that it has grown since then--during a year of antipsychotic treatment. All the while, the information that those drugs are linked to such tumors was out there... and I don't think my doctor had a clue.
And I have a pretty good doctor.
I wake up every morning with my heart beating out of my chest, with feelings of absolute horror. Maybe a similar sensation?
The only medication that has helped with this is Tramadol, which is a pain medication that has side effects on the adrenal system. These medication "side effects" treat my panic attacks better than any psychiatric drug I have EVER taken and without the side effects. (Cannabis works too, but that's illegal so we won't go there...)
I took Vistaril for a while, and that wasn't bad, until it started making me have the same reaction as the other drugs, which consists primarily of limb twitching, panic, skin crawling, pins&needles, and just serious psychic pain.
SEROQUEL is NOT a drug to be taken LIGHTLY. Nor is anything else the p-doc prescribes.
AND MOST IMPORTANTLY exercise has been proven by science to be about 20x more effective than the leading antidepressants. And often diet and unknown food sensitives are also implicated in mood problems. So changes in those two tend to go a lot further than taking a pill that just makes you sicker.
So at this point I'm still waiting on seeing a neurosurgeon and endocrinologist, who are incredibly difficult to book appointments with... You might have more luck with an endrocrinologist than with a pdoc for the symptoms, depending on what they are and the cause. It's probably at least worth a visit if you've never seen an endo.
