I've never used S-33 so I cant really speak to that, but the one thing I've found with EC1118 is "patients is a virtue"! A week just to get started has not been uncommon (I know there is a lot of conflicting information to this, but that's just my experience). I don't know how long it sat before deciding to re pitch, but my advise would be to look away for a couple weeks before even checking again. If you bottled now, and IF the yeast is still viable, and IF fermentation is truly over, then the same amount of priming sugar should be used as you normally would for the carbonation required. That's a lot of "if's" and to me is a perfect recipe for some really cool beer volcano's!
