Probably a couple of weeks (and they weren't major), with flashes every so often after that as my body continued to adjust. I kept reminding myself that my brain had been completely wired to that stuff and would take a while to re-wire itself. However, since my taper was a lot more gradual than yours, your side effects might be more intense for a while. I just kept reminding myself that it was ok -- normal, in fact -- to be experiencing what I was experiencing and that it would pass. Which it has. Hang in there!
