Maybe some simple descriptors, with like a barely/mild/moderate/heavy/very heavily tag:
- You are mildly experiencing distorted perception and hallucinations.
- You are moderately experiencing decreased aches and pains.
- You are heavily experiencing increased appetite
- You are barely experiencing decreased inhibitions
- You are very heavily experiencing jitters and increased energy
The categories I would propose off the top of my head might be:
distorted perception and hallucinations - LnA-3z, nA-3z
decreased aches and pains - Dez, Endo, Nevadone, v-202 (maybe LnA? the wiki says it is an opiate)
euphoria - LnA, nA, Dez, TH-2c, jackel pipe
feelings of superiority and indestructibility - v-202 (and maybe mRc? It seems to act like cocaine/meth)
feelings of aggression - v-202, jackel pipe, mRc
feelings of paranoia - TH-2c, v-202
reduced inhibitions - mRc, TH-2c, jackel pipes
increased appetite - TH-2c
jitters and wakefulness - mRc, EverUp, Ex-D7
increased intensity of sensations - mRc
decreased empathy for others - v-202
These are just some suggested ideas, and I'm sure people have others. In general, though, I find it hard sometimes to figure out what effects exactly I am feeling from drugs (especially recreational drugs) at a given moment, and having some guidance would be awesome.
I suppose you could expand this to other effects, too, like PDS and other diseases. When having a PDS outbreak you might feel 'feelings of aggression' in addition to the occasional PDS message emitted to you.
