Hi Lost and Welcome,
I also had blackouts when I was drinking and I dismissed them as 'not that bad' for a long time. In truth, blackouts are terrifying. When I really stopped and sat with the idea that I had no clue what I had during those hours, who I was with, where I went, money I spent, I was horrified. Thankfully, neither of us have to go through that again.
