Does lorazepam cause blackouts?

That's wild that your experiencing black outs at just 1mg and for 2 days! Wow. Are you taking any meds that would interact with the ativan? Or drinking at all? The only thing I can think of as to why 1mg causes you to blackout is mixing meds or maybe your body just converts differently and it's too much for your body to handle.

Yes my friend It can, I was put on Lunesta which basically the same as any benzodiazepine medication.

I slept walked for a few nights where I went to sleep but awoke unknown to me because I found juice or such on the counter. I monitored it but that quickly stopped and I also became immune to it too.
