Atkins and the ECA stack?

I'm currently on Atkins and have been for about two months now. I've lost some weight, but it seems that I have come to a stall, although I do believe I've lost a few more inches than what the scale indicates. I read online about the "ECA stack" which consists of taking a set dosage of ephedra, caffeine, and aspirin (all done in moderation.) I am NOT asking for people to preach to me about the dngers of ephedra, caffeine, or aspirin. I am asking if anyone has tried this and what their results were? I'm wanting to kick up my weight loss a bit, and also increases my energy. (That strong burst of energy from cutting carbs has recently started to deminish). Has anyone tried this and did you notice a difference in weight loss and energy? Thanks
