An addiction simply adheres itself to our self-belief eroding it gradually by digging into it. We just remain a shade of our previous selves hereby taking a short cut to a track that leads us to more acute physical and mental problems.
Any addiction can be overcome, any bad patch overridden if only we could endure it by facing it head-on keeping the following lines from Kipling in mind...
"If you can fill the unforgiving minute
With sixty seconds worth of distance run
Yours is the earth and everything that's in it
And – which is more – you'll be a MAN! "
