Hi,

I am new here and this is my first post. I don't know if this has 
been discussed in past, so please let me know if so.

My question: After a person has been given veritaserum, how do you 
end its effect? Does it wear off after a while like polujuice 
potion? Or maybe you have to cast a spell like enervate? Or maybe 
the effects end when you ask a certain question? Maybe there is 
something like antiveritaserum which you have to drink? What do you 
all think?
