Mixing lsd and shrooms (and other psychedelic combinations)

[sleep]

Anyone have any experience with mixing LSD and shrooms? I've done both individually, and they seem like pretty similar substances to me, but I'm wondering what the difference would be between mixing them together and simply taking higher dosages of each individually. 

Also, as a more general question, what combinations would you guys recommend and which substances are better not mixed together? I've done candy flipping before, and it was not a good experience, got way too horny but I wasn't able to handle my own emotions which led to some very ucomfortable situations with other people lol.
