I Have Been On Methadone Maintenance For About 15 Months.

I have been on methadone maintenance for about 15 months. Due to $ I have to stop and have been reducing mg by 10/week. I'm down to 40mg, cant go everyday, and want to ask to reduce down to 30mg this week. I was scheduled to go into a 4 day detox, but on my way there they called n questioned me and said my withdrawals weren't severe enough. How much longer should I continue doing the clinic every other day, and are there any over the counter meds/herbs, etc, that can help with withdrawal?
