i know that the chlorpheniramine maleate in CCC's helps to intensify the trip. i recommend taking 16 c's and then use robotussins for the rest. i know that anything over 700 mgs is a pretty hardcore trip. I took 1500 mgs once for a 4th plateau trip and it was completely different than any other plateau. auditory hallucinations, and extreme visual distortions were present along with total mind fucks where i forgot who, and where i was for minutes at a time and actually was wondering if i was alive or dead. its an amazing experience, but if your not strong minded i wouldnt recommend it because my friend broke down and was crying. the trip also lasts for at least 12 hours and the after effects are felt for up to three days at that dose
