For certain people I believe that Provigil is or can be addictive. Both physically and mentally. I started in 2005 on around 200 mg for jet lag and I had to go to detox last year to get off of it. The increase always happens. When I take Provigil I do get a 'rush' similar to that of cocaine but much less instense. In the past I stole a prescription to get more. There are times in the past that when I just stopped using it. I have cravings for about 3 days and I was very unmotivated for about the same. This to me sounds like addiction and I think people should know that this is a possibility.
