When I tried stopping after the 5mg dose I had constant vertigo symptoms and incredible difficulty sleeping.
What I ended up doing was cutting the pills in half for a few weeks, then quarters, then removing one day a week from the schedule until I was down 2.5mg/wk. Finally I was able to stop, and only was mildly affected for 3 weeks after that.
That stuff does weird things to your brain. On the flip side, I couldn't have gotten through some really rough times without it.
