I haven't heard of this to prevent the symptoms of allergies. What specific allergies are you targeting anyway? I did read something on bodybuilding.com to the effect of taking in something like 10000mg to avoid getting a cold/recovering from a cold. Taking 2000 seems like regular supplementation and am not sure it would have the same effect. I can't find a link to the article now but i'm sure it was based on a research study.

With that said, who the hell would supplement with that much Vitamin C. And I believe there are some serious health drawbacks with taking that much versus the benefits of fighting a lousy cold.
