Ah, we have Splenda, which has sucralose in it, but if you're not keen on it...but then maybe try to get used to it because:

Actually there are problems with Splenda, too, bu I can't recall what.
There is Stevia, but it has a bad aftertaste. I use agave syrup. It is mildly sweet, so if you like your coffee sweet, it could get expensive.
