Mike - It sounds like your body rebelled to the increased dosage of one or both meds - hard to tell which one. Drug tapers are nothing to mess with, so believe these members. The safest way to do it is to get a taper schedule from your doctor, or better yet, a pharmacy specialist. Especially when trying to taper two drugs at once there could be a bunch of unpleasant symptoms.
Are you trying to stop both meds, or just reduce to a lower dosage? Have you talked to your provider about how to manage it?
