Slowly... very slowly. It sounds like you made the decision to go from 200 mg to 100 mg unilaterally (i.e. have you talked to your doctor about this yet)? It may be that you need to taper more slowly. Instead of going from 200 to 100, maybe 200 to 150 (or 200 on the odd days and 100 on even days). Or you may need to stay at the 200 mg level a little longer before the next reduction. There are options.

Everyone is different. There are several threads about this topic, and many stories—you are not alone in this, and there IS light at the end of the tunnel. The light may be a little farther than it appears—tunnels can be like that—but it is there, and each step gets you closer to it.
