I would've said that it sounds like a great idea but the thought of intentionally causing more brain damage ontop of all the damage that was already done doesn't seem particularly safe. Assuming that only the memories of getting injected with Invega are forgotten, I'd most likely find out sooner or later why I suddenly don't feel the way I used to. For example, I'd wonder why I was on this site in the first place, then read about everything I typed and realize why I feel that way. Or someone would eventually bring it up since basically everyone that has known me before/after Invega is already aware of what occurred to me, and they'd probably be like, "hey how are you feeling after this much time off of Invega"?
