I created a potty training monster. Help.

DS1 is 3 years 1 month.  I tried to start training him early fall, but he had no interest, so I stopped for a couple of months.  I tried to start back up again in the beginning of December, but I wasn't consistent b/c we were always on the go with holiday events/parties/shopping etc.  Too hectic.  So we started again yesterday.  I decided to do a sticker chart, which he loved.  and after each time he peed, I gave him a few Skittles.  At the end of so many times of peeing/stickers, i told him we would go to Target to pick out a treat.  Well, yesterday, he peed 5 times and stayed dry all day!  My problem is that he is now obsessed with the Skittles.  Like, he will pee, we dump the potty, wash hands, he eats his Skittles and then he jumps right back on the potty and then FREAKS, I mean has a royal melt down, b/c he can't pee again.  This happened all day yesterday, a few times today (only b/c he had preschool part of the day).  Tonight we went out to dinner, and he had ice cream for desert.  Came home and said, actually demanded, that he wanted a lolly pop and then he was going to sit on the potty.  I told him if he pees, he's not getting any food/candy, he'd get a big hug and I'd chase him around the house- I had to think quick! 

So, in a nutshell- I don't think he cares about using the potty as much as he does the candy, but it's the only thing that motivates him, as I have been trying off and on for several months now, and just started the Skittle rewards.  What do you use as rewards?  Or should I start by not giving him a reward everytime he pees?  Or is he too early in the game to not be rewarded each time?  Maybe I need to make a trip to the $ store for more prizes?  Please help, I just want to do the right thing without turning him into a complete candy freak.  he's on his way now.
