Welcome to HCM
taking any benzodiazepine
with alcohol in your case xanex or diazepam
results in additive effects of both drugs or cocktail effect. It causes severe sedation and retardation of mental activity. Some times may cause delirium
like condition. haldol was given to you to decrease violent aggressive behavior at that situation.
So kindly avoid such type of use in future and if you are at risk of cardiac arrhythmia
then it may prove fatal.
So be cautious in future.
Hope I cleared your doubt.
