IUD thoughts? Experiences?

Julia
Hi guys, so I've been on the pill for 5 years now and I was considering the IUD. I'm in a relationship and sexually active. I like the idea that you don't have to worry about a pill, or remembering. Anybody have the IUD? What do you like about it? What don't you like about it? 
I want to get the Paraguard also know as the copper IUD. No hormones. 
Thanks ladies!
