Oddly I never ended up redosing again. 7 hours since that last dose now, I'm almost baseline but not quite, still have a tiny bit of residual stimulation left over. The comedown was surprisingly easy but I think sticking to 2 doses was behind that, when the comedown started I felt the urge to redose but after that left I felt quite good, relaxed, more like my initial dose than the rushes I got after the second one, but pleasant nonetheless.
Got half a beer and some rum left so just going to drink, maybe get stoned, and then head to bed
PS I found the trick that stopped me redosing again was just to do things, as soon as I became focused on an activity time went flying by and the next time I checked the clock 30-50 minutes had passed, and as soon as I felt the urge to redose rearing its head I distracted myself again
Looking forward to trying this again soon, maybe oral this time though since the snorted duration wasn't quite as long as I wanted, at least with the peak.
