Do I understand that you are changing your dosage without consulting with your care team? If so that is something I would not do and so I have no experience in arbitrarily cutting the dosage.

As for my dosage I started out at 5mg in the morning and 5 mg in the evening just after my transplant on 12/30/19. Now nearly three years later I have stabilized at 3 mg in the morning and 2.5 mg at night. The positive from any reduction was less cramping but then that was moderated by magnesium supplements.
Best always,
