Note: This is not to brag or to belittle your experience, it probably depends very much on the individual.

I went cold turkey from 150 mg (after years of use) and honestly, even a mild flu would have been worse. The ringing and the zaps were just a minor (and expected) annoyance, and a small dose of pain killer took care of the headache. The only surprise was completely losing my patience for a couple of weeks, I was raging and bashing things (not people, thankfully) for being a trivial hindrance.
