The pain when I had my IUD taken out was stronger than when I had it put it, but it was very fast. I flinched, then it was done. It'll be over before you know it. Worrying about it up until they did it was probably worse than the actual getting it taken out.
I've heard a lot of good things about the vitamins Rainbow Light makes. I bought some that are food based and you take them three times a day - it helps with absorption. You can buy them at Whole Foods.
Good luck!
