I think the reason that Alice says she is not her self is cause she has changed so many times in one day that she does not know who or what she really is. Also there was the cook that kept on throwing things the reason was the little baby liked the sound of the pans flying bye. Alice finds a mushroom that could make her grow taller and shorter all on which side of it she eats so she eats some of the mushroom to get taller. I think the reason that Alice would drink from a bottle that says drink me is she expecting it to do something good for her. All the things that she used before help her get taller and or shorter. This is why i think she drinks something that says drink me.
