Hi and welcome JayPray
I think it's normal to fear all kinds of things after a blackout...
For me, blackout memories were almost completely gone, never to return. I hope that nothing happened, tomorrow is a normal day, and you can move on.
For me the worst thing you could do with blackouts was get used to them. Once I had one they kept reocurring.
I've never had to deal with the problem since I stopped drinking.
I hope you're considering the same?
