You might experience symptoms such as nausea, sleep disturbances, appetite changes, etc. Once you are stable on half the
tablet, you can go in for alternate day dosing of the half
tablet for the next two weeks. This has worked with many, though there is no standard way of taper off.
You might also try reducing the dose gradually by taking it with fluids, such as orange juice. You might choose to reduce 25% each week, or more gradual if symptoms appear.
