Here is a response I received on another addiction board:
"Addiction is a disease of the brain.....And yes the physical will improve.....
It never stops, it goes into a sort of remission......The longer a person is in recovery the farther removed they are from falling back into hell again......but it doesn't mean that they can't/won't.
There are many who relaspse, after years clean and where they were when they left off, they get right back to and real quick......
Here are some interesting links on addiction and the neurology of it all....."
