Can the regain coupons be used immediately? Lily gave half of her cookies to her housemates, including oatmeal raisin and white chocolate macadamia. So, I'd like her to forget that she's a witch for the memory loss but regain some of her magic at the same time so she'll be confused why she has these powers.

Since she's new, she doesn't really have significant in game memories to lose yet and most lost memories from canon wouldn't have a noticeable impact on their own with her lack of castmates.
