Alcohol + Plan b???

Si..I’m an alcoholic.. I’m 23, childless , not sexually active and definitely not on any form of Birth control. However one night I went to a party, got super drunk and had sex without a condom! That night I took a plan B because I’m not ready for kids at all!! Should I take another plan B since I was intoxicated ? Or should I be fine ?! PLEASE HELP😫😫😫
