You should be concerned. After ten yrs of being told its safe and not addictive I could that I was addicted. Ended up with gastroparesis after losing 35 pounds in one month. Horrible withdrawal including restless legs and my legs would actually bounce on the bed at night. Doctor just said to stop but found that I had to restart and decrease slowly. Now they are admitting that this is an opioid and addicting. Discontinue before you have the lifelong issues that I now have.
