Talk to your Dr first and be very careful. And like they said, taper off slowly. It's a super addictive medication. I had only been on it for 6 months and didn't think I was addicted to it and I forgot to get a refill and my withdrawal symptoms from missing one dose the next day were terrible. I had to leave work, and I couldn't function. So I would advise against just outright stopping.
As always you should take to your physician when deciding to taper off a benzodiazepine. 1.0 mg/day isn't a huge dose so you shouldn't have too many problems coming off of it as long as you don't go cold turkey.
I was at 1 mg/day for about 2 months so I didn't have the long-term use that you did, although I had been taking it "as needed" for a couple years prior. I had no problems coming off of that 1 mg/day by cutting them in half and taking that daily for 2 weeks, and then taking the 1/2 every other day for another two weeks.
Of course, individual results may vary. Your taper may take long and may involve more increments than that.
I would be inclined to reduce very slowly. Can you cut it in 1/4s? Ryan is a great one to ask about this. He is very knowledgeable.
