I've never blacked out.. Did you mix other drugs or alcohol? For us we just tripped and smoked a bunch of weed. We had some enlightening, motivational, self discovery type trips and it kind of felt like a black out because all these great thoughts and plans just seemed to fall back to the part of the brain where they're stored and forgotten about after we finally crashed out and woke up the next day. It's crazy how productive you are on acid, I've drawn some crazy pictures on that . I've made digital music where it felt like I was able to paint the notes exactly like I saw the patterns in my mind and I don't know about the proper way to write music
It really is similiar to the limitless movie IMO
