I can say right now because I am not taking it because of upcoming surgery ,I definately dont like it without it.
So could "I" survive without it? lol not very well and definately not for long, so yes I would say their is a dependency gained to it by being on it for a length of time, which usually happens with other drugs as well.
Addicting no I wouldnt say that, addiction is much worse than dependency in my opinion.
But I do supose it depends on a persons perspective, my perspective of addiction is you get so enthralled with whatever you are addicted to, and it makes you do anything to have it.
I was /am/still do have a couple addictions however I have gotten them under better control, but there was a time I would/did spend every penny I made to have it (it wasn't illegal drug), I even pawned stuff to get more for it,and after I had a big adreniline happy rush I always felt guilty like I did something wrong, definately not the same as becoming dependent on something.
