As I am currently stuck home (with really no way to get out with my sprained ankle) the daily updates will continue for a few more days.
Today, I can definitely say that I'm aware of how loose my top aligner feels, which makes sense as I'm scheduled to change to the next set on Monday. I never really feel the looseness in the bottom (although there's a lack of pressure, but it's always more obvious for me in the top.) I think this is partially because I have less holding the aligner in on top (7 attachments - on the canines and pre-molars for anchorage mostly - one for rotation), so I feel it more there than on the bottom where I normally have 14 attachments (except for where one popped off yesterday). I wouldn't say the bottom is loose but there's definitely not any real pressure anywhere.
My pain/annoyance is more from my sprained ankle at the moment than the aligners although I find I keep falling asleep with my leg elevated and waking up with dry mouth a few hours later. The upside to being injured and sleepy is that I'm not eating much so I'm easily meeting 22+ hours a day of wear time. So I think I've made up for any reduced wear times in this set so far.
The virtual bite ramps are less annoying now that I have three instead of four. I expect I'm going to have to deal with these beyond the next set because of my deep bite, and until things start to line up more in the back and touch. (Probably six months minimum is my estimate.) However as they're different on each set and can be different sizes and depths hopefully they won't be the annoyance I ran into on the first set again. Right now, I have three - two on the left, on one the right and they're not sharp or anything. If I do find a sharp one, I'm going to treat it like a sharp edge on an aligner and take a nail file to it to smooth it a little.
I really have not gotten used to the attachments on the bottom with my aligners out. It just constantly feels like I have something stuck to my teeth. Particularly in the front - so it makes me want to go brush, floss, waterpik and stick the aligners back in ASAP after eating. Good for compliance, I guess but even when I know they're not trapping food they still feel foreign. Of course, I also have a history of getting food stuck in my lower front teeth anyway (aka the mess) when eating so this might be why I feel like this because attachments there kind of mimic food being stuck there for me.
I will say that flossing has gotten a LOT easier and that there's not a place that I can't get floss into which with the lower crowding was NOT the case before I started.
After breaking off an attachment yesterday, I've been reworking my strategy on the bottom tray for removal. I don't know if that attachment came off from the way I was removing the trays or that it was already weakened from chewing biting since it was on a molar.
I've gotten pretty used to what is essentially a mouthful of plastic. My lisp is pretty much gone now and the whole process of eating has become second nature. A little annoying - yes, but second nature. Considering what I would be facing had I gone traditional braces (Ie, a bite plate/molar buildups/bite turbos at a minimum in addition to brackets and wires), I think I really got off easy.
For those with Essix retainers, I imagine this has to be somewhat similar - aside from the attachments and I know the invisalign aligners are thinner and there is a certain degree of flexibility to them to get them in and out. Yes, they can be broken but I've stopped worrying so much about cracking the aligners when putting them in and out since they seem to stand up to normal forces. Also, I'm pretty certain they get more pliable with wear. '
I had a friend pick me up ginger ale and diet sprite yesterday so I can try some clear ocean experiments (for science

As always happy to answer questions, I think I might've lost some more weight too but I'm not getting on a scale until I can use both legs
