Addiction #3

Why is kicking an addiction hard, beyond the physiological reasons? Say, for example, a caffeine addiction. Caffeine enables a lifestyle that is impossible without it. One can do more of whatever one pleases. The cost, of course, is the come-down (although this can be made to fall at convenient times), as well as health risks eg kidney failure. Part of why kicking the addiction is hard is because you have to sacrifice the lifestyle benefits, and change your habits, and perhaps even your work/life balance...it's not only the chemicals themselves!
