I'm going to use an analogy here that I think may put it in perspective. I hope there are alot of car nuts here.
You work your ass off for years and year just to get that (insert exotic car here). You finally get your Porsche and although your previous car was fast, it just didn't have that look or performance of the Porsche. A Porsche is engineered. In your opinion, Dudes wanna be you and chicks want you while you drive that car. You drive the piss out of it for a few years and enjoy it like it was nobody's business. This was your dream after all. Slowly but surely you'll get bored with the car. You have two options. One, buy a newer, faster one (up the dose) or two, because of changing priorities in life, buy a mini van (get off crank).
Since we're discussing going clean, you've picked the mini van. Do you ever think about back in the day while driving the van past the young dude in the Porsche with the pretty blonde? Hell yeah! Probably even lust for the thrill again but you've been there and done that. Life changes and so do your priorities. Addiction is state of mind. So long as you have a grip on what is important in your life you'll always be fine.
Hope I didn't offend any natty's with the mini van comment. I'm sure there are alot of natty's out there who are probably closer to Supra's, or RX7's or mustangs... but let's be honest.... no such thing as a natty Ferrari, Porsche or Lamborghini. There is a look (and a stigma) that accompany these rides that no other vehicle has.
