It seems like people's chemistry and personality play into it a lot. Some people are able to maintain Dr's direction and have no big issue coming off prescriptions. Others get so wrapped up in it, physically and mentally, that they can't break free. Some fight it until they're dead or in jail and still others like it so much that they have zero intentions of ever stopping. It's a terrible reality that torments the very souls of most people who find themselves in the situation.
More research and much more product transparency should've been offered to everyone involved before putting such a powerfully addictive drug in common reach of most of society. Alternative maintenance medications are also extremely addictive, but becoming drug free seems like an impossibility for many in the cycle.
For those fighting it, there is hope. Just 1 day at a time and pretty soon a year or two have passed and it all will seem like a bad dream.
