I can't answer you as I had to stop drinking sodas all together. Diet or
otherwise. It seemed to bloat me up and give me stomach aches. When I
stopped drinking diet soda, the stomach cramps went away completely. I also
seemed to lose alot more weight quicker on weeks where I had no soda.

Sucralose is allowed on Atkins (it's an exception to the "ose" rule as
it's artificial).  Plain/essence seltzer is a great choice though.  If
you really want a sweetened carbonated beverage with meals, you can try
the seltzers sweetened with Sucralose and Ace-K or add some of the
syrups that many of the regulars use (DaVinci) to plain seltzer.

 Give up the sodas for 2 weeks.. come on you can do it!

To be honest with you, I think I would just stick with water as much as
possible and shelve everything else for awhile.

Some have no problems with the Splenda, others report stalls that they can't
attribute to anything else (but that doesn't necessarily mean that the
artificial sweeteners are the cause).  It just seems to me that artificial
sweeteners leave too many questions unanswered, and the only consistent rule
is that YMMV.

That was a legitimate rule because sugar names end in -ose.  The Splenda
people screwed the rule up by naming their product sucralose, as if it
were a sugar.  It's not a sugar though, so the rule doesn't actually
apply.

Normally, ingredients ending in -ose are actual sugars: sucrose,
glucose, dextrose, maltose, lactose, etc.  Sometimes products claiming
to be "sugar-free" are only sucrose free, and have other sugars as
sweeteners.

McNeil named their sweetener chemical "sucralose" to sound like a
sugar.  It's an exception to Atkins' rule of avoiding -ose.

It's possible that sucralose might technically meet the chemical
definition of a sugar (I don't know for sure), but -- the fact that it's
600 times sweeter than sucrose means you'll never get enough of it to
have the effects of a sugar in your body from it.  One gram of actual
crystalline sucralose would be equivalent to more than 3 cups of sugar
in sweetness.

Splenda packets or 2 teaspoons of the granular only have a few milligrams
of sucralose.  The rest is a gram of carb padding, so that you don't have
to measure your Splenda with precision tweezers.  Splenda in most
products, especially liquids like diet soda, use pure sucralose in
manufacturing, and not the padded form sold to consumers.

Also, newbies often mistakenly believe that the Splenda granular has
more carb padding than packets, because it has more volume.  It's made
in fluffy, airy crystals to match the volume of sugar, but if you crush
2 teaspoons of bulk Splenda to powder, it crushes down as small as the
contents of a packet, and they both weigh a gram.
