Morphine requires more cycles to put you to sleep (#4094)

## About The Pull Request

Pushes the amount of cycles needed to put you to sleep on Morphine to
around ~10+ units rather than the ~5 units it was before.

## Why It's Good For The Game

Morphine was used more as a direct sedative than a combat painkiller,
getting it lined up more for what it was intended for
