Any experience with suddenly stopping lamotrigine?

To celebrate my 50k party, I got a nice rash over my torso, front and back. There is a rash associated with lamotrigine that can kill you, but it usually happens when you first start the medication, not three years after you started. Even so, my psychiatrist suggested I stop the med pending a visit to the dermatologist.

I see my doctor this afternoon, and I’m pretty sure this is not a side effect of the drug, but meanwhile I am experiencing some strange effects and I’m wondering if anyone else has had anything like it when they suddenly dropped a medication.

I feel very wooly and buzzy inside. Like I have a cold, only without the other symptoms of a cold. It’s been about 36 hours since I took my last pill. It’s hard to think and concentrate, and I just want to lie down and sleep.

My head feels like it wants to have a headache (but I don’t have one yet). It’s not pleasant. And my skin feels like it’s buzzing a bit all over, too.

Anyone ever dropped lamotrogine (Lamictal) all of a sudden? What happened?
