Ever have one of those mornings when you think you are losing you mind? So, when just before I went to bed last night, I put my invisalign retainers in as always. This morning when brushing my teeth, I glance down at the retainer's storage container and it is empty. I run through what I have done this morning and do not remember taking them out. I guess I took them out in my sleep, which is no easy thing since they securely snap into place. Spent 15 minutes tearing the bed apart and still cannot find them. Looks like I will be tearing the bedroom apart when I home tonight in an effort to find them. Fun times!
