I don't seem to. I am on 75 mg, but seem to not experience withdrawal with that particular one.

Have you previously been on 75 mg? If so, and it did not help at that dosage, then lowering the dosage may be an issue.

If the medication is tapered down and not suddenly stopped, the experienced anxiety shouldn't be withdrawal per say, but rather that severe anxiety coming through.

If you haven't been on 75 mg for a period longer than a few weeks, then maybe it will help? If anything, it should help a little bit unless the anxiety really trumps the lower dosage.

Voice your concerns with the doctor. If you feel that you are not ready for a lower dosage, then he/she should take that into account.
