I'm really interested in dissociative drugs particular K and mexxy but I've noticed tolerance builds rapidly. I'm thinking of ordering 4 big bottles of robotussin for dry coughs avoids that nasty shit in the rest. Would that be enough for a high 3rd low 4th plateau trip. I've done it numerous times I love the CEVs it gives walls closing in on you and the drunk like feeling on low doses. Most I've done at once was 2 big bottles and a small one but for full blown dissociative effects is it as enjoyable as K also plateau sigma seems hard to achieve and from what I've read highly scary and can only be achieved by redosing over hours
