Atkins Diet question. 10pts best answer!?

I have been on the induction phase for 1 week now. I read you are allowed 3 packs of Splenda a day. I already used 2 this morning in my tea does that mean I can't eat an Atkins bar later? Aren't they sweetened with the same ingredient? If so how many packs do they count for? Also is it OK to stay on induction for months instead of 2 weeks? I have a good bit of weight to lose so I want to do it the most efficient way possible. Thanks for answering!
