All you do is chop everything, except leave small cluster of buds on the lower branches. So basically you can chop every branch down to the last bud site (or two), which is usually pretty small anyway, and stick it in the veg room. It will take quite awhile to bounce back. The leftover buds sites will start turning into really ugly leaves and then it takes off. I'm guessing you will harvest 95% of the bud, so you really have nothing to lose from trying, that is if you have the time and place to do some vegging.
