Update: Drinking session on Sunday, November 26, and the recovery
Side effects: The side effects weren't as bad as I remembered them to be, and that is very good news for my long term commitment! Especially the nausea was a lot better. At the end of the night, I was almost throwing up, but that was probably because I felt "I had had enough". Other side effects were feeling slightly dizzy, less appetite (isn't such a bad thing for me really, as I eat more than enough to begin with), some muscle spasms, fragmented sleep, feeling of being cold, and night sweats.
Drinking session: I took Nal at 14.30, and popped the first beer at 16.00 (next time I will wait the full 2 hours just to be sure). I mindfully started drinking; the taste felt pretty much the same, but I didn't have the physical sensation of the alcohol "hitting" my nervous system, so to speak. I went to the meeting after consuming 3 units alone. There we were drinking steadily. I gave away some of my beer to the others, since I was unable to say no, and we were going out anyways. When I had run out, I started having a massive craving. It was partially satisfied at the first bar we went to, but they were closing up, so I could only have one small pint. After drinking that, the craving intensified, and if it weren't for the fact that we were heading to another place downtown Oslo, I would probably have gone to the store to buy the 2,3% beer cans that they're allowed to sell outside of the normal buying times for alcohol. Anything to satisfy that craving.
When we arrived at the second place, I immediately ordered another beer and started drinking. Eventually I bought another one, and at some point, drinking felt less and less tempting, and this last one took a long time to finish. The last mouthfuls I merely finished because we were leaving. After leaving, I realized I could've gone without drinking up (which was probably done more out of habit and not wanting to waste precious money, as the beer cost 90 NOK = 8,3£), and felt slightly nauseated. When we were on our way home, I didn't feel any compulsion to drink anymore, and I went to sleep.
I consumed a total of about 14 units, which isn't that much for a binger like me, especially considering I had been drinking for about 10 hours that day. Usually, and especially when I have been deprived for a long time, I would probably consume more than 20 units and blackout/brown out and would have to be followed home. This time, I didn't have any blackouts, negative moods, and nor did I do anything reckless. In fact, I had a whole lot of fun, and had the giggles several times. When compared to drinking without nal, I noticed I felt less stressed out, and as I was approaching satiation, I wasn't stressing out about having more available. I also got more tired from alcohol as opposed to that euphoric feeling and having to drink more.
Recovery: Since I wasn't sleeping before 4 am, I had to sleep until noon before feeling ready to meet the day. I woke up quite a few times to drink water, and while I felt like sleeping all night, it was harder to stay asleep. I didn't have any mandatory classes today, so that was no biggie. The hangover wasn't bad at all, compared to what I've had before. The day has so far been spent on reading and doing some other errands. Appetite has definitely been a bit lower than usual. If somebody invited me out to drink, I believe I would decline that. The last year when I've gone on benders without Nal, I would often start the next day by mindlessily drinking whatever alcohol I could find/go to the store ASAP to buy some. I will try to do some exercise tomorrow, as I will be "supersensitive" to endorphins at that point.
All in all, I'm very happy about how this went, and I'm excited to see how quickly my cravings and intake will decline.

I believe I will be drinking again the upcoming weekend, or, if I don't feel like it, I will postpone drinking until a trip I'm going on Dec 6 - 8. But I will be sure to take Nal first!
