Update sleepiness_mod drugs to use effects.json

[TRScheel]

Is your feature request related to a problem? Please describe.

I believe it would be better if item id's pills_sleep, poppy_sleep, and chamomile_tea utilized effects.json for their sleepiness_mod modifiers.

Solution you would like.

Implement a new effect in effects.json such as hypnotics (see here for its medical definition) that these items use instead.

This would allow those drugs to better represent their real world counterparts. It would let CDDA model how they affect your mental/physical capabilities and how there is a real risk of death from overuse of them (ie. popping 100 at a time).

I am recommending a staggered reduction in:

• Perception
• Dexterity
• Intelligence
• Speed

Additionally, I'd put in a risk of death after a certain amount of use (to be determined).

Describe alternatives you have considered.

Could use the iuse.cpp methods for this but that hard codes all this and this feels like it should definitely be a json item. Alternatively, could just ignore it completely.

Additional context

I plan on implementing this myself (if approved ofc), just opening this up to discussion as to what values would make sense and be reasonable.

What will cause this effect? Drug-Effect or Drug-EOC-effect or Drug-vitamin-effect? Or other options?

My intention was to use the same mechanism that painkillers are currently using. I cited the dermatik effect because it actually has the sleepiness mod values in its definition, but painkillers would be the drug analogy.

We are wanting to migrate away from drug effects to drug vitamins. So that would be the system of preference to use.

Can you point me to some examples of this that I can use for reference? You don't need to fish out the actual code for it, I can look it up myself. I would just appreciate knowing what is considered a 'good example' for the drugs moving forward.

I've been told I'm not good at being concise. So if you can get through the wall of text, maybe this will help you.
#77022

And I'm not sure what the developers consider to be a good example. Maybe this: #70239

Thanks, I will review it.
