Trying to taper off kpins while on methadone

So basically I was wondering if what im doing will work. Been on methadone for about 15 years and currently on high dose(over 100mg) but I've been taking klonopins for several years to help sleep. I eventually got to two 1mg kpins everyday. I've been trying to taper for about 2 months and currently I've gotten down to 0.5mg per day. So I have like 17mgs left and have been on the .5 for almost 2 weeks. How do I finish the taper and do I have enough to taper properly? Btw im on methadone also but i really want to stop having to take benzos to sleep
