Hey.

Memory Potions have been used on the show Once upon a time several times. Rumplestiltskin even reveals two ingredients of the potion in the episode A Curious Thing. Rumplestiltskin said the following in the Curious Thing: ''"Wolf's blood and dragon's scale. I've tasted that brew before." ''I'd say that suggests that these are ingredients which are always added to the potion.

Zelena added a forgetting potion to the Dark Curse which Snow White enacted. As a result the citizens of Storybrooke forgot an entire year until the curse was broken. Zelena mixed herself a memory potion to remember that year. When Rumple created the Dark Curse for the Evil Queen  he added a forgetting potion and thus made sure that the residents of Storybrooke forgot 28 years of their life. Rumple once drank a potion because he knew to much about his future. (There's No Place Like Home)

I'm wondering how you can make sure you forget the right time periode? Just imagine, drinking up the potion instead of only forgetting that Hook and Emma managed to travel back in time,  Rumplestiltskin forgot a longer periode. I mean, is it just a matter of the dose you drink? Are there specific ingredients to add in order to forget five, twenty or more years?
