Since the answer to the question "How long does it take before a vampire NEEDS to feed?" varies from source to source, I figured I would ask here to get a few opinions on the basic nature of vampirism, as it is by D&D rules.
Would a Vampire technically suffer from starvation after a certain amount of time, or would they simply be driven mad by the overwhelming bloodthirst? How long would it take for anything like this to occur?
Mind you that I'm fishing for opinions here, as there doesn't seem to be any definative answer. Of course, if there is and I'm just not seeing it anywhere, by all means let me know. Anything you may have to offer is appreciated. :]
