I've asked this question before on another site but no one seemed to be able to answer it. So I'll ask you guys.
If what happened to Sammy actually happened to Leonard, and it was Leonard who gave his wife the insulin overdose, how does he remember giving her the shots?
He couldn't have remembered because it was after his accident. And even if there was a faint chance he remembered the exact moment his wife died, he couldn't have remembered giving her the shots over and over again, because if that was the case, then he would've realized it was fatal and thus not done it.
