Not to be tough on you, but this is possibly the worse question I've heard on here. What do you think is going to happen? You can't have a whack across the head and forget it all, the past is with you and if anything - your a dweller.



Even people with post-traumatic-stress-disorder don't do this, sorry if I'm judging too quick but this is just too risky and can cause a lot more neurological and brain-related complications.How can I make myself forgot something or give me a slight touch of amnesia?
