How'd the trip go? Was it really weak? That was a light dose you took. I really got into that stuff back in 1st semester of college. No money, no drugs, except my card to the grocery store. I only got the Robo extra strenght cough syrup, The one that has the most DXM per serving and it has no other active ingrediants. Anyway, I did it a bunch of times. Everyone I knew that did it would drink one bottle and I would always drink 2. One of the days I researched it hard on erowid.org and then drank 3 and a half bottles of the extra strength cough syrup, I think the amount was around 1500 mg. Was tripping really hard but it was like my body was TRASHED drunk and I could just watch things blend together in the room. Trying to talk on that much was almost impossible and chronic just brought me to a completely different level. I'd suggest, not to do it though, acid is just sooo much better
