need usable suggestions about zoloft effects

Hi there--I started 25mg of zoloft 2 months ago for anxiety disorder, and had manageable tremors, unmanageable insomnia, and occasional headache. My psychiatrist doubled that to 50 mg three days ago. I now have severe and sudden eyebrow and eyelid pain with pins and needles and tight muscles all over my body and uncontrollable shivering (like I'm cold) about 3-4 hours after taking the dose--about lunchtime. The headache then moves up my forehead to the top of my head and i get blurry vision and cant think very well and cant talk without effort. This lasts about 2-3 hours, and I can do nothing for it--So I called the psychiatrist who was covering for my regular psychiatrist and he said this will happen for a few days--he said sometimes it can be like a migraine and it is not stroke or vascular or high BP. He said if it doesnt go away in about 5 more days to go back to the 25 mgs.He said it was a serotonin reaction or some term like that. I need reassurance that this is safe and will pass. I live alone and this greatly impairs my ability to read for very long or have a conversation or make decisions, etc, so I'm in no position to call in sick at work. i will say my emotional anxiety is much improved and my mood is more stable (needs work still, though), so I'm reluctant to quit zoloft altogether. I need some specific feedback/options that I can use in the next few days.Thanks for your help, nyl

If I were you I would go back to 25mg, and then by cutting the pills in pieces, add 5 mg a day . You may be so sensitive that the right dose for you is somewhere between 25 and 50...
