Addon that informs you about player interrupts?

[TotemsAreGreat]

One thing that prevents me from playing a caster in pvp seriously is because interrupts are hard for me to keep track off. They very brief and quiet sound it makes is not enough for me to notice when the other player used an interrupt and I constantly live in fear of using any spells other than instant casts.

Is there anything that can make it more obvious when a player uses an interrupt when you're trying to bait it out?

Once you've been interrupted it's already too late, and all interrupts that I can think of are instant casts.

A player can cast their interrupt without actually interrupting your spells. I just need to know if they've used it when I'm trying to bait it out. The little quiet sound it makes is just not enough for me!
