I was on it about 1 1/2 yrs ago, when it was brand new for RSD in my right leg, i hated it. not only was i so disorianted and it upset my stomach, but i couldn't get out of bed, it gave me visual disturbances, i couldn't see anything, and i gained 30 lbs. i stuck with it for 3-4 months, the pain was still threre (not as bad) but the side affects did ot out weight the benifits for me. so i came off of it. and one time i ran out, and could get ahold of my doc to get the refill, so i went through terrible withdraw symptoms until it go filled again. so yes, you can get addicted to it.
