There are definitely withdrawals when stopping sub, however, they are nothing compared to what I experienced when stopping Percocet. Sub was a life saver for me. I think the key is to try to stop asap. I think the longer you take it, the harder it becomes to stop. And those of us that are taking it are addicts and we can become dependent on anything. While everyone experiences something different, I never felt the depression when I stopped. And because you don't get high from sub, I didn't feel the need to wake up and take it first thing in the morning.
