Honestly that's a pretty low dose, I bet you could easily taper off that. A schedule I might try is dropping 2.5mg each week, so one week is 10mg/day then next week 7.5mg/day then the week after 5. I also might make sure that one of the doses is taken at night to help with sleep. Its hard to sleep while going through withdrawals. Your doctor could also provide advice and support as well if you discuss it with them
