I’m afraid the knowledge isn’t enough. The brain is prone to addiction, since it’s a highly effective system also for all the beneficial regular stuff we do. Alcoholics who do fight that can’t have a sip until the end of their lives. That strong system it is. A nice book about how it is for the addict on a socially accepted drug wrote Matty Perry from The Friends, before he died. Usually books on addiction are about hard drug addicts and I never felt the connection, but this one got me.
