I know where you're coming from and many medications have terrible come-downs. Different types of meds produce different effects on the body when stopped or cut down. It also depends on the person of course.

If you are still on the path of stopping, you're doing great with a taper. Maybe you are going about it too fast. But i praise you for tapering, as it will make the detox much more doable. Only your doctor can help you when it comes to dosage and whatnot. But you will most likely feel nasty no matter how you go about this. But the slow taper will make it easier.

Yore doing great and I hope things get easier. Dink plenty of fluids, vitamins and food.

Take care and best wishes.
