I've not been fortunate enough to indulge in any 4-sub trypts

well, aside from 4-HO-DMT, but it's no RC by a long shot lol
4-subs are pretty wonderful. 4-HO-MET and 4-AcO-DMT are probably my faves of the ones I've tried, but I have yet to try one and be disappointed.
The Louvre is incredible. I didn't fully comprehend how
fucking huge it is, and every room is overflowing with amazing exhibits, from ancient Sumerian artifacts to modern masterpieces. I only got through most of one wing (out of 3, I think?) today in ~4-5 hours. Called it quits a little early because A) I was getting tired from all the walking and didn't want to wear myself out before the weekend, B) I know I'm going back at
least once anyway, C) my airbnb for my last couple nights in A'dam canceled on me and I wanted to get back to my laptop + wifi to book another one, and D) my phone was running low on batteries and I have little faith in my ability to navigate Paris without Google Maps, or remember the door codes to get into the building I'm staying in without checking my email

I think I took about a hundred pics on my phone, mostly in the first couple hours... Eventually I realized that I had neither the time, battery life, nor probably even the storage space to take photos of everything photo-worthy in that place. Hope my airbnb host doesn't have capped upstream or anything cuz uploading those to the Book of Faces is gonna use quite a bit, lulz.
If you have the slightest interest in art, architecture, history, and/or European culture and ever find yourself in France, don't waste your time gawking at the Eiffel Tower and Champs-Élysées until you've blocked out at least two days to visit the Louvre. As someone with an interest in all those things, it's basically Disneyworld for adults. And I made it through the day speaking French almost exclusively, despite my vocabulary having atrophied to a couple hundred words or so after a decade of not reading, writing, or speaking the language much at all. I figured the whole 'immerse yourself in a foreign language to (re-)learn it faster' thing would take weeks, if not months, to make a real difference... Nope. Day two and my French is already coming back. Magnifique!
Saw a guy around my age on the Métro ride home with an Adventure Time hat, neck piercings, and some pretty elaborate hand and neck tattoos. If I wanted to find drugs in this town, I bet he coulda helped me, heh. I think I'm just gonna save my money for the coffeeshops in A'dam and keep up the tolerance break, though. Turns out I don't jones for weed so much when I have interesting shit to do during the day, and tire myself out enough to sleep without chemical assistance. I was craving a bowl like a motherfucker in Pompeii, but I'm doing just fine without any in Paris. Still have a little benzo solution if I need help sleeping (although I ran outta empty gelcaps so I have to squirt it directly into my mouth - alprazolam is bitter as fuck, even in a glycol solution that helps cover up the taste), and chain-smoking cigs like a proper Parisian is enough to satisfy my oral fixation (a dated concept by American psychiatric standards, I know... But I am in the country of Lacanian psychoanalysis, after all ; ).
Time to find an airbnb in A'dam for my last two nights that doesn't require a big security deposit in Euros (a lot of them want 100-200EUR deposits for keys, but I'll be going straight from checking out of this rezzy to the airport to fly back to Chicago - seems stupid to keep a bunch of Euros on hand for a deposit only to have to pay to change them back to dollars as soon as I get the deposit back) and allows smoking and/or is near some good coffeeshops. Wish me luck!
