They are very tough. I inherited one in an overgrown garden once and cut it down, thinking that I would eventually get round to removing it. But it sprang back and I was happy to let it grow on again. Here is something from the RHS website
"If you inherit a garden full of neglected shrubs or have a plant that is overgrown and choked with branches, you can try to rejuvenate it by pruning.
Some shrubs can be severely pruned just as growth begins in mid-spring. Spotted laurel (Aucuba), box (Buxus), camellias, Choisya, Euonymus, hollies, Pieris, laurels (Prunus laurocerasus and P. lusitanica), Viburnum tinus and yew all tolerate severe pruning to near ground level.
Other evergreens are often best renovated over several years, removing one-third to half of shoots to ground level, and reducing all other shoots by one-third in the first year. Over the next couple of years, each year remove half of the older shoots to ground level."
I'd leave it just a little while until the spring revs up a bit but then go ahead. But use sharp tools to ensure that the cuts don't become infected.
