Out of Potions

Hey guys, this is probably going to be a dumb question....but I'm fighting the beast right before I get to Yunalesca, you know the crazy one where you can change your locations to the other floating rocks. Anyway, Im completely out of potions, and I was hoping I would find Oaka's little friend before I got to this guy, but alas....I did not. So, my question: Obviously I won't be able to beat this guy with no potions whatsoever, so what do you suggest to be the easiest way to go about getting some? Will I have to walk ALL the way back to the last time I saw that guy? Any help would be appreciated. Thanks, guys!

I think you would have to go all the way back to see wantz (oakz`s ,mate) but by then potions should be obselete!!! wot are your hp lvls?

Wantz isn't there when you go back down the mountain is he? You can always use Yuna instead as a White Mage or go back down to the Calm Lands.

That's why you should use Pray more often.

It's free you know.

Also let Rikku "Use" Al Bhed Potions. However, I rarely had less than 99 of either kind. *shrugs*
