Loud and powerful sneezers, have you figured out a way to tame your sneezes?

I sneeze really loudly and powerful and often I can't control it. What makes it worse is, its often sprays a lot of saliva as well. I'm safe most of the time if I can get to my handkerchief or tissue in time. But there are times I have no other option but to let it out. Has anyone found a way to tame it and make it milder or easier to control.
