On the bottom I wore my retainer 24/7 for about a month. And that was basically because I was still doing my top teeth so just kept wearing the bottom as well. The top retainer I only had to wear full-time for 2 weeks. I have had no problems with my top retainer at all. Mild tightness at night when I put the retainer on. On the bottom, however I have noticed more problems/shifting during the day. My ortho told me not to worry about it if the discomfort was short lived (which is it). Now some people on here have had to wear their retainers full-time for a lot longer. This will depend on your orthodontist.
I did have refinements which I was disappointed in to begin with, but again it went so fast it really didn't affect me and I am so glad I did it as the final "touch up" has made me very happy. It added about 2 months to my overall time which compared to how long I'll have this smile, is nothing.

I was never shy or uncomfortable with my smile or anything like that. My case wasn't what some consider "severe," and I didn't really notice the crowding/wonky tooth except in pictures. It took a profile shot of me at my nephew's birthday party for me to finally pull the trigger and do something. Since having them however, I look back at those pictures and thank God I went ahead and did it.
I'm glad I did it and would do it again, but am also happy that I don't have to
