Suggest Treatment For Giddiness And Seizures After Alcohol Intake

hello, my girlfriend and i were at a bar last night and she had a moderate amount of alcohol to drink. the amount was nothing short of a normal night for us. near the time we left the bar she appeared to be heavily intoxicated. within 20 minutes she became very aggressive, giddy, and uninhibited. about 40 minutes later she experience full body seizures/convulsions that lasted for about 1.5 hrs. when she woke up this morning she had no recollection of these events. what could cause something like this?
