From my personal experience, my meth addiction started out as having a good time partying on the weekends. It didn't become a daily thing until I was told I needed to "step it up" at work. I started filling capsules with meth and popping them to keep up a busy pace. I was promoted because of my fats pace, but i became addicted to the drug. Eventually, I was smoking it in the bathroom and in the company vehicle. I had used drugs socially for 20 years. A little coke every now and then, ecstacy once in a while, but nothing had ever hooked me until meth. I do not feel that I had a disease or any of that B.S. I just made some dumb choices. Thankfully, my family noticed the massive weight loss, and strange hours i was keeping and got me into a program at Narconon (www.stopaddiction.com) and I've been clean for over a year. For me, the mental addiction was the hardest thing to beat, I had no physical withdrawal, I just had to relearn how to cope with the demands of a busy life. I don't even drink energy drinks now. The caffeine in Diet Coke is the strongest stimulant I use. This addiction can be beaten.
