I was watching Ugly Betty last night. Willimina’s sister is now in the show and she is dating Daniel the director of the magazine. Anyway Willimina switches her sister’s pills with some other pills and after a week her sister starts going crazy. She becomes overly obsessed with Daniel and gets so jealous so easy. She’ll throw tantrums over nothing, and it turns out she had these problems before and she ended up murdering her boyfriend. But what I was wondering is, is it really possible that a person can flip that much that fast just by getting off these pills? Or is this show just over exaggerating things?

It seems like it could happen. There's been numerous school shooting because of people getting off of anti-depressants.  I don't know if the timing on Ugly Betty was like in the same day?  I think it might take a few days at least...

I guess if a person really has a lot of imbalances it could happen.
