I came home from hospital with codeine and paracetamol. Both are pain killers.
Don't confuse codeine with caffeine. Caffeine in your coffee is a stiumland. codeine is a pian killer. It has the opposite effect. Caffeine wakes you up. odeine send you to sleep, hence less sensivive to everything outside and inside, including pain.
I slept all afternoon. I thought that meant I was getting old, and dying.
Then I read the insctructions with the pills. I knew how many to take and how often. That was on the outside of the paceket, on a sticker.
The Instruction leaflet icluded the side efects. One side effect was feeling sleepy. That explains it.
No driving. No drinking with the pills.
Different pills are used for different maladies. And different amounts for different ages and weights. Be guided by your doctor. However, by reading background inforation, you may be able to ask relevnt questions, and to notice side effects.
