My understanding is that Splenda and other artificial sweeteners are just that - artificial. That's why you should give them up. If you want to sweeten your coffee just put a bit of raw sugar, or honey in it, or something like that (I know sugar is processed, but there have to be some that are better than others).
Don't think of it as cheating since this way of life is not about looking around the corner for the time when you can have your next cheat, just accept that you are okay with 5 grams of sugar everyday in your coffee. If that's all the sugar you are eating it's not a big deal and it's better for you than the fake stuff.
