No far from easy. if it was easy noone would be addicted. While you may only be sick for 5 days or so thats a very very long 5 days
Comparatively it's an easy withdrawal, unless it's methadone. In regular opiate withdrawal, the worst is over in 3 or 4 days and it's pretty much all done in a week. Methadone will run for weeks.
Cocaine and stimulants have you feeling horrible for a couple weeks, and then not so horrible for a couple months.
Benzo withdrawal will string you out for weeks, and can kill you.
Alcohol withdrawal kills people all the time, and causes hallucinations, seizures, brain damage (Wernicke's encephalitis), heart attack and stroke among other things.
When I was addicted to oxycodone during recovery from a serious injury, after 4 days of withdrawal I was fine. Yeah I sweated, shook, had diarrhea, threw up, couldn't sleep, couldn't eat. But honestly it wasn't that bad.
Alcohol withdrawal put me in the hospital, admitted to the ER, with seizures, and abnormal heartbeat, blood pressure of 190 over 110, heart rate of 120, hallucinating. Luckily I never got Wernicke's encephalitis because I took lots of extra b vitamins - thiamine prevents it.
That's why you don't go cold turkey off alcohol. The crazy thing is that you can go into alcohol withdrawal just from cutting back. You never know how much is too much to cut back. Anybody with more than a moderate habit, meaning three drinks a day, is at risk for alcohol withdrawal even from cutting back.
That's also why alcoholics are petrified of missing a drink.
So yeah all in all regular opiate withdrawal is pretty easy.
