Long term effects of Benzodiazapams OD

Recently I overdosed on Temazepam 30mg (took 1740mg) and Ativan 1mg (took 13mg). Although I was sent to the hospital, the drugs were in my system for almost an hour. Will there be any problems regarding this incident in the future. My potassium level dropped dangerously in the hospital, but that has been corrected. I'm not sure about any other problem in the hospital as I can't remember it, but any information for the future would be appreciated.
