Cutting ativan daily dose

Am currently titrating ativan taper and have managed down to 0.290 mg divided in two daily doses [daily drop of 0.0100 total]. Should I continue the twice daily regimen

until taper complete or could I just go to once in the morning or night. If at a low dose and go to once daily will interdose withdrawal be an issue?

Because of its relatively short half-life, I would not recommend 1X day dosing with Ativan.

Thank-you builder. Will stay with 2x a day. Any suggestions as to when I could "jump"? 0.1 mg a day seems negligible. Think safe to stop at 0.05 or best to run down to zero. Appreciate your thoughts
