The last I heard, kratom in capsules can be very unreliable (as in they can sell bunk shit). I would always purchase pure powdered leaf. But yeah, tolerance can be an explanation too.
OT: 6 AM, butanediol-slept for a few hours (I call it that because I never sleep more than 3-4 hours when taking it, due to the very short half-life and rebound). Feeling kinda good considering I'm about 40 hours off codeine, and by this time it gets bad. I only intended to take one day off, which I succeeded in doing, and in about 2 hours I will be eligible to go buy me some, but I'm debating whether I will do it or not. After a day break, the high will be amazing, and I don't want to continue withdrawals until fullblown (48-80 h) because I gotta work tomorrow. So yeah, probably going to get some soon. For now, drinking 1,4-butanediol.
tl;dr 3 ml 1,4-butanediol, might take some codeine soon.
off-topic: had some interesting dreams. Very vivid and I can still remember after waking up more than an hour ago. Funny thing is, I was acting the dream after waking up for at least a few minutes. As in, I was in a bed in the dream as well, so I couldn't really tell the difference - I mean I knew I woke up, but I kept seeing the same shit around me (easy when it's dark in the room) that I was in the dream. Wasn't the most pleasant of dreams, but at least I got a chance to get it on with a girl, so I guess that's alright, lol.
