I weigh 130 pounds and have some tolerance to DXM due to frequent use in my youth.
Had a mild trip last night, ate a bottle of robitussin pills and downed some Delsym. What I did was drink a few shots of Delsym then eat a few pills... waited, nothing about an hour later, so I finished the Delsym and took three or four more pills and kept waiting... and hour later, still nothing, so down goes a shot of vodka with the rest of the pills. All I had was a body high, which wasn't doing it for me, so I slowly bumped it up. About an two hours from initially dosing (should have really kept track of time) was when my trip really started. I melted in with the blackness of my room and in with the music I was playing on my headphones a little after my vision began to split.
As soon as I reached the realization that my ego was going to split as my CEVs began, I felt a little worried, and I lean over and filled a garbage can about half full with garbage. After that, I felt a little more clear-headed and enjoyed entering memory states. Something I've noticed with DXM: even with my eyes closed, I feel like I can see my keyboard as if lights were on, or I can look around my room turning my mental head around, and I can see everything perfectly. I went then through my memories, all of them incredibly lucid including some even I'd forgotten. My "dreams" were very spiritual, some of which involved me losing my body and "meness" and blending in with something like God. I also felt overwhelming love for so many people.
The trip really began around 19:00 and I was able to think clearly and move around again near midnight. I brushed me teeth and went to bed (was difficult, as I felt quite stimulated). When I woke up the next morning at 7, I felt really shitty. I could hardly focus at work and felt like I was going to barf a few times. I probably spent twenty minutes just sitting in the bathroom during my lunch break just resting my face in my hands. After a small meal when I got home and some lying-down time in bed (16:00), I feel totally refreshed and healthy. My sluggishness carried on still, however...
It was a strong trip, and one which I'm sure could have certainly been improved without the vomiting or Delsym. Not as great as many of the third plat trips I've had before, but still more satisfying than a second plat one. Interesting to note is that when I "came to" I was in the middle of a Skype call with a complete stranger. He turned out to be a nice and cool guy though. He said that I was really high and repeated some of the visions I'd experienced as I'd apparently been chattering the whole time.
