1) yes you will be nervous just like any type of procedure you will be put under. However when you think about everything you have been through to get to this point you will be excited to be here. At the office they make you feel at home so they ease your nervousness immediately.
2) I did bring a neck pillow also however I really didnt need it. I use it more now at home the I did in the office. I have trouble sitting with the dilators in so I just sit on the pillow and it makes it so much better!!!
Just relax and know that when you leave there your life will be changed forever!!!!
