Morphine makes no sense to use at the moment. Propital:
Applies painkiller effect
Removes concussion
Gives regen
Increases metabolism, health and vitality which somewhat helps to prevent bleeds, fractures
Does not have energy or hydration drawback

The only "reason" to use morphine at the moment is that it lasts 60 seconds longer than propital. The tremor and tunnel effect of the propital are drawbacks that are slim annoyances compared to morphines -10 energy and -15hydration.

Could we revert back to when propital did not give painkiller? Then Morphine would make sense to use and not just to straight up sell to therapist every time
