Do you really wear your trays 22 hours?

I’m on tray 4 of 20 I felt like it was controlling and affecting my meal times so I don’t do a timer or rush my meals I just make sure to put them back on after I’m finished eating. Each tray is tracking still and they feel loose when it’s time for a new tray. I feel like my teeth are moving faster then expected. I feel like I’m doing more so 20 vs 22 hours a day. Also I’m seeing a lot of people having to do refinements and now I’m freaking out if I’ll have to pay more for that since I paid in full😭
