I'm not sure why, exactly, you think you have a better chance going off of it "cold turkey". You have been taking it for 8 years now. Quitting a benzo cold-turkey is not like quitting smoking. You are at risk for seizures, rebound anxiety, headaches, tension, depression, insomnia, confusion, dizziness, personality changes, tachycardia, heart palpitations, hallucinations, memory loss, panic attacks, etc.
Sound like something you want to do cold-turkey?
