I wore my retainers religiously for months, and then I backed off on them because I realized that they were leaving a sizeable gap between two of my front teeth. They are squeezed back together now, and still look quite nice. One of my bottom teeth is a little messed up but hardly worth the fuss.
My wisdom teeth were removed last summer (all 4) so those won't be around to crowd anything up.
Also, I hated my dentist so I went to another. After my first cleaning he told me I had A LOT of cavities that my ortho told me was decalcification. Even 3 cleaning visits afterwards, the old dentist never recognized any of them.
So the new dentist got in there and gave me 4 amalgam fillings on one side. They were huge. Hige to the point that one of my molars suffered pulpitis as a result of the massive filling. Now I have a tooth with a root canal and rubber filling, and I have to wait until January to get a crown because my insurance maxed out on ALL THE FILLINGS.
I can't even describe my anger at my old dentist for not finding those cavities while they were small. Now I can only chew on the right side of my mouth for several months until I throw out hundreds, if not thousands for a crown.
And I couldn't wear my bottom retainer if I wanted to anymore because I don't have all of a tooth anymore
Edit: Here's a recent picture. Teeth still looking straight despite not wearing my retainer
