Tapering off should be at a schedule that suits you, not some generalized one that your psychiatrist does for everyone. It's also usually, though definitely not always, best to do this with a psychopharmacologist, not a general doc, just because they do it a lot more often. Now, you don't say if you're taking them every day or several times a day or just as needed, but still, safe is best. Don't quit abruptly, as that can lead to worse withdrawal and possible seizures.
