so glad you did it!!
Just stay positive. The first few days/nights will be uncomfortable, but you will make it through. I know the feeling of 'i finally did it'. Now the waiting starts and the anticipation of how your nose will heal will be the hardest to deal with. Make sure to take pics of when you have your cast removed and then take pics each month. So you know how your nose changes from month to month. I had my surgery done 3 months ago. Keep using the arnica gel and palettes. They do help a lot!!!
The swelling that is on the forehead now will continue down your face. Just make sure to relax and keep your head elevated. I know, you won't be getting much sleep but it's for the faster healing.
Keep us posted and show us before and after of your nose in the next months.
