In my story, a drug called "lucy" has been rapidly gaining popularity for its effects, primarily something similar to lucid dreaming. The drug is taken before sleep and supposedly allows the user to be aware in their dreams.
Where it backfires is that it doesn't actually put you to sleep, but I'd like that to be something that isn't immediately apparent. Eventually, the lack of sleep and averse side-effects (as yet unknown) result in insanity.
I'm working on very sparse knowledge of drugs, but I think the type most like this would be hallucinogens. I was originally going to use for a base something like mushrooms, but I'd rather the tripping out be somewhat coherent. It will have some surreal qualities, but not the exaggerated kind you'd get from mushrooms or something similar.
Does this sound like a realistic drug, and also, would it make a difference what form it was in (liquid, powder, pill)?
Thank you in advance!
