10 mg instant release. The extended release (XR) formula would help me for the first half of the day, but after about noon all effects would have worn off. Asked my doctor to change from 20 mg XR to 10 mg twice daily. And no, it is not a whole lot, and I am trying to keep it that way. As mentioned before, if I could do without it, I would.
