Several people already said that... or also DOI... I haven´t done any of the DOx so far, so I can´t tell! But in those good old days, friends of mine tried DOB in high doses. They claimed, that this stuff came extremely near to acid.
Flow: IDK about DOB specifically, but I must have talked to you before about my DOI experiences. I *guess* I probably took a fairly heavy dose the first time(3 days of tripping with a few days after effects) and to compare DOI to LSD would work if your idea of good L is being all sweaty, clenching teeth, and having *extremely* dull visuals. I'm not a big fan of feeling tweaked I guess it might be some people's kind of thing though.
Yeah, I guess that the DOx act very different in different people. Some reports look like "almost acid" experiences, other trips seem as far away from acid as possible. I guess the problem is, that most people have really big problems measuring the dose accurately (see also the "scales" thread!). When it´s DOxs, 0.5mg more or less can make a real big difference!
Well what could it have been besides DOI or DOB? I can't think of anything. Maybe drfly I guess but doubt it. At first, unfamiliar with DOI, I thought it may have been 5-meo-amt, but someone more experienced with that substance told me even high doses don't really last that long. I was told it was DOI a couple days later anyways, before I had even really heard of too many people having it... I tripped for three days and the way I felt was just like all the reports I read.
