Scared of getting hangxiety again

I’ve been drinking most weekends for a little over a year. Usually 8-11 standard drinks 1-3 nights. I’m 22 years old, 6’ 220.

Three weeks ago I had 9 standard drinks within 1.5 hours like an idiot, then an hour later had 2 more. I don’t normally do this and idk why I did. I drank no water, threw up, then fell asleep.

The next day I was severely dehydrated which gave me bad heart flutters which let to panic attacks and I didn’t sleep much for like three days, felt awful.

My question is basically can I expect similar things to happen again? I’m scared to drink honestly. I’ll definitely drink water and take my drinks slower but maybe I’m just anxious I’m going to have more panic attacks. I hate those things.

I’m 100% recovered from it now, normal levels of anxiety, sleeping well, no heart flutters or shortness of breath. I’ve never had a hangover be that bad ever and last that long.
