How do I replenish MP's?

[Roxy1001]

I'm in Tyrine and I can't get out. I can't replenish my MP's unless I sleep at the inn and before I had to go to the house to sleep. Is there a skill that allows you to replenish both HP's and MP's?

You can always buy Mana Potions from the girl(forgot her name :P) who's at the bottom of the screen where you challenge Louis to a match (the screen with the town hall )

EDIT:The chick's name is Rebecca

Magicka Potion and Magicka Energizer.

And there are unique items like ocean love yveen tear and such but they are rare and don't use them unless you REALLY have to.
