Ativan addiction ....please advise

I was diagnosed with a chronic disease five years ago.  I was taking Ativan 1mg in the morning and 1 mg at night before the dx.  Last year my doctor my increased the dosage 2 mg in the morning and 2 mgs at night for extreme tinnitus and anxiety from the disease.  I also take two vicodin 5/500 a day.  Once in the morning and once at night.
I started tapering down to 1.75 in morning at 2 at night.  Can someone Please help me figure out what is the best way to taper down properly.  The addiction issue is causing me enough stress.
