You can take these benzodiazepines as needed but you may build up a tolerance and feel some withdrawal if you don't take them. Benzos are dangereous and hard to get off of. If you don't NEED to take them I would advice you not to. Benzos have screwed up my whole central nervous systom. I don't mean to scare you at all. I would just listen to your dr and ask questions if you feel you have to.
Best of Luck,
