I am on 40 mg Ziprasidone. I love this stuff but I plan to try tapering down to 20 mg, the smallest dose it comes in, to see if that would be enough for my needs.

yes, they are capsules. So if you need less, do what people do with capsules: open them and use half the sprinkles inside the capsule. I assume inside are sprinkles. Not sure, I have never opened them. Maybe it is powder. You can dilute it in a glass of water, mixing / stirring really well, and then drink half that cup at a time.
