A friend of mine posted this on Facebook the other day, with her permission I wanted to share it with everyone: "Its basically as if you are living on borrowed happiness, instead of it being spread at a steady rate, throughout the days. You take a drug and feel amazing, but it's always borrowed; you will always have to pay up, eventually. You take it once, one day and youre high off of 10 dollars worth; The next few days, you're at 30 to get that same feeling; soon, you're tolerance is too high to afford that high - and you're stuck paying the piper. The more you try to hold off paying back that borrow happiness, the more it costs you; worse and longer withdrawal and a tolerance too high to hold back having to go through it. Sooner or later, you have to come down; tolerance makes it practically impossible to keep that feeling going indefinitely: sooner or later, your tolerance will hit the point where you can't afford that next fix and when that time comes; it's time to pay up."
