According to David it's in the "Your Call" category . . . . . SPQP page 170. The theory is that once you are over withdrawal you won't crave sweet tasting stuff any more.. It  is so for me most of the time. But I still don't like coffee without it. I use "Splenda" , which many people don't approve of. But it amounts to one little tablet a day so I think I can live with that.  All those listed as "unsafe" in SPQP  are best avoided.  

There is a new product on the market, I think it has been around for awhile now. It is called Natvia.100% natural, it is Aspartame, saccharin and Sucralose free. Has no artificial flavours. Comes from the Stevia plant, looks like sugar. I bought it for cooking, and can't taste the difference. Though once you cut out the sugar, you don't miss it, though it would be a good alternative while cutting back. It is also an all Australian product. My husband still has sugar, and I put it in his coffee to see if he noticed the difference, and he didn't. There is no after taste as there is with some of the other alternatives. I found it in the sugar section in my local supermarket. Though not all seem to stock it, had to look out for it when I first went looking for it.
