Ok, so the come-up didn't start till 1.5 hours after ingestion, whereas usually (with a lower dose, too) it takes 45 mins. The peak came on quite quickly, which made up for the long onset. I then peaked for about 6 hours, riding the waves which are so characteristic of 6-APB. There were slight visual distortions: morphing, and brightening of light and colour. I didn't trip as much as I usually do, probably because I'd taken 25I-NBOMe 5 days prior to this experience - thus draining my 5-HT2A receptors (responsible for tripping).
The roll was very good. I didn't have any nausea at all, whereas last time I tried 200mg I had slight nausea for about 5-10 mins (didn't vomit though). I did have diarrhoea during the come-up and the day after, but literally every single drug gives me this (usually just during the come-up). My body did get very hot, however, and has been hot for all of the following day. Taking off my clothes was sufficient to keep me cool. The weather is unusually hot right now, and normally heat isn't too much of an issue - more of a nuisance, really.
200mg really is the sweet-spot for me. 100mg was unimpressive, 125mg was comfortable but nothing amazing, 150mg was getting there but still nothing to be excited about. YMMV, of course, but I personally feel that the various dosage guides that can be found online are quite a bit low.
Also, people judge how high they are by how high they've been before. I usually don't dose any drug high enough to be considered "unsafe" - if one could say that - but I have had a few extremely intense experiences. Thus my self-analysis of how high I am is much stricter than that of someone's who hasn't dosed a drug high before. To be honest, I'd much rather be satisfied by lower doses than have to dose medium-high all the time, but my very first drug experience was almost an overdose (due to incorrectly giving trust of dosage to a friend), thus my expectations have been high from the very start.
My dosage philosophy is very simple: start at medium-high, and then increase until I feel that increasing more would give a low effects/side-effects ratio. Also, I only redose on stimulants. Drugs like 6-APB last pretty long, leaving me very satisfied and not wanting more. What's more, the come-down comes in waves, too, so it's never shocking or disappointing when it happens.
