Set 4 is in...barely

Ready for aligner set #4.  Almost ready for bed.  Teeth brushed and flossed and fluoride rinsed.  Now to put in the new aligners.  Let's start with the lower.  First try - won't go in, second try, they click in - victory!  Super tight.  Now the upper.  First try - not even close; second try - right side clicks in, but left and front not working.  Now to try a little more muscle - right, lllleeeeefffttt...click, push front up as far as I can without really forcing it...  I guess it is in.  Ouch.  Now to try a chewie for a few minutes to get it to seat better in the front.  Then some tylenol and bed.  Hope the morning is better.
