Snoring all the time can indicate something a little more serious like slept apnea. If she doesn't stop when you nudge her or she rolls over, the only other alternative is for you to couch it!
My wife snoring keeps me awake and I use the highest earplugs to keep from hearing it and works part of the time. What can do relax when this happens so I get some sleep?
Memory foam earplugs have worked for me with my partners resonating growling at night. Maybe try a form of white noise.
