Weaning off of aripiprazole (Abilify)

My doctor wants me to go cold turkey off Abilify 10mg. I'm terrified to do it. I've tried twice and gave up. She won't prescribe it for me again. But, I do have 3 months of refills left. I'm thinking of splitting the pill in half for 5mg. Then try that for a month or so and then splitting that 5mg in half and then go from there. Has anyone had any experiences doing this? The doc thinks the Abilify is making my shopping addiction worse. I agree. I'm on so many drugs. I feel like a walking pharmacy. I'm so tired all of the time and I've gained a ton of weight as well. Sux.
