Well first of all thanks to the people with some positive input. No thanks to the people who called me a douche for being ignorant and then went on their merry way, LOL.
The only contact with 'acid' that I had before this was a love/hate thing.
I recall very little about the first time I took it except that I took 1 hit and decided 'you know what I feel pretty good, I'm gonna take another two' so I went for a 3-hitter on my first time. Our friend decided to drive to Best Buy for something and I came for the ride. All I remember is that it was difficult to do everything (body movement) and I was very shaky and weak. This feeling seemed to come and go but was pretty persistent, and I just felt flattened and useless. I ended up throwing up into a bag he had in his car and what came out was a big red blob. I told my friend that I had just vomited blood, and he tried to explain it away as a hallucination. I assured him that I was still rational and seeing all colors just fine, and that I swore I had just vomited a giant glob of blood from my stomach. We narrowed it down to some pills I had snorted the night before tearing up my throat and me having bled from a lesion, but I still wandered from the couch to the bathroom for the next couple of hours thinking I might be dying. I wouldn't classify it as a bad trip, but I did think that maybe my stomach erupted and I might die for a good few hours before calming down. After that I just remember having epiphanies and colors seeming to change in front of my very eyes., and just being able to hang out, although detached from others.
The second time was nothing but fun and euphoric coz I was calm, prepared, in a good place and only took a hit or two and brought two roommates along for the ride (for free). I also did this while coming down from the E we had taken during that night/morning. We just giggled for a few hours, made fun of what was on TV, and watched the Christmas tree 'dance'.
I recall it having been fully onset within about a half hour to an hour both times.
The stuff I just got seemed to set on fast at first (quicker than an hour) and go at full potency after a couple of hours from taking 1/8th tab followed by another after some light fasting. I thought I had the real deal. However, I was on a full stomach the next time I took a full quarter tab and it seemed to take 2-3 hours to onset, and I researched that LSD does not behave this way and has the same onset time without regard to what's been consumed. The time afterward (full half tab) it also seemed to depend on how much I ate, taking between hours 1 and 2 after dosing for full onset.
So I'm just really confused right now. I don't have much of a baseline if any at all. There is a type of DOx that has full onset time based on how full you are (sourced from Erowid), and this seems to fit the best description.
I will tread lightly with this stuff though. Thankfully, I'm not one for multiple-hit trips after my first experience.
