lorazepam, and lessens the chances of
unpleasant effects when you stop taking them.

these signs occur, they usually do not last long.
If you do suffer from any of these signs, ask
your doctor for advice.

might have more serious withdrawal signs,
such as loss of sense of reality, feeling unreal
or detached from life, not able to feel emotion.
