A similar thing happened to me, I freaked out and called my pdoc. He arranged for an emergency appt and advised me to go to a clinic. I obliged, my meds got tweaked (not anything drastic, jis added an anti-psychotic, well IMO that;s not drastic) and the only time I've experienced something similar was when I was "clever" and skipped my meds for 2 days...

just wanted to let you know you're not alone, and also, I don't think the ride to the hospital will be a circus(ambulance and what not) or futile. It could be the answer to your prayers. It sure was mine, and I only stayed for 2days...

Also, this was not the first time this happened to me, granted the occasions were few and far between, but it definitely got worse for me. thus me freaking out the last time...
Not sure if this helps any...
