Are you sure it's tardive dyskinesia? There are other movement disorders that can be caused by antipsychotics that aren't TD, and some can be controlled with things like cogentin.
If you still can't reach your doctor, see if there's a crisis line for a psych ER in your area. If it's really bad, you could go inpatient, where they might be able to wean you off a lot faster, since they can supervise you medically in that situation.
It's not a great idea to wean yourself off of meds unsupervised.
I would wait for your doctor. I'm weaning off of geodon right now too. I've been going down 20mg a month from a 120mg start. Are you on any other meds? If you are, it may be the other meds that are causing the TD.
I'm on it too. From what I've read its very hard to get off of. You have to wean yourself off very slow. Google it. I would do 170 for a week. Minus 10mg a week. I'm starting tonight too. Please google how to wean yourself off of it. Good Luck
