What sort of zombies are we talking here?
Airborne mutagenic virus zombies, a la Resident Evil movies? If this is the case then the fact that I survived the initial infection suggests that I have an immunity to the zombie virus. If you are immune to smallpox it doesn't matter whether you breathe it in, drink it or someone with smallpox bites you, you won't get it, despite some methods being obviously more alarming than others. If this is the case then I still need to go to a hospital because the necrotised flesh of the zombie, plus the diseases in the mouth mean that I'd need to be careful of infection from normal viruses, but not the zombie virus.
Traditional West Indies zombie, as animated by a bokor? If this is the case then as long as the bite doesn't kill me I don't have to worry (see above for dealing with normal infection) A bokor can only reanimate the dead, and the curse doesn't spread at all.
Infection spread solely through bites? Again, there's always a chance of immunity, but still, it's about what I can afford to lose to survive a zombie apocalypse. Losing one arm is fine because I can still hold, fire and load a pistol one handed, plus opening doors, eating and other concerns, but losing a leg presents more of a problem, because then I have to think about getting around the place. Probably if it came to that I'd amputate the leg as fast as possible, then see if survival still looked likely (probably by holing up somewhere well fortified and waiting for the military to roll in)
The only reason zombie movies have any elements of horror to them are a combination of Hollywood science and mass holding of the idiot ball. A basic understanding of viruses lets you know whether you have the potential for immunity or not, and after that any knowledge of field medicine and weapon handling and you'd be basically completely okay unless you got surrounded.
And if the Hollywood science really had come to life and animated these zombies, then I'd still hang on. Having been alive while everyone else was becoming a zombie would have given me a chance to see what the transformation process looked like, so I'd know whether I was undergoing it, and would probably kill myself. If there were no symptoms except just keeling over dead one second and raising the next, then at least I probably wouldn't be self aware anymore, so I'm as good as dead anyway.
Applying science to zombie settings never goes well.
