I haven't tried saliva. Usually I just end up with my mask way up my nose and my glasses moved down my nose. That works fine short term but I have to hold my head like a pompous asshole and that's tiring.
The 3M "Aura" N95s have a generous and durable nose pad that's basically eliminated this problem for me. They do get extremely humid on the inside though; I have to carry two and swap them every hour.
