I'm doing a 21 Day Sugar Detox right now myself (today is my first day, so far so good - but it's also only 10:30 - ha ha). Though I will say, from the research I've read from whole foodies, agave nectar as sold in most stores is only a little better than HFCS. It has similar chemicals involved in processing, and a similar reaction in our bodies. I primarily use raw honey, organic maple syrup and molasses as my go-to sweeteners now (and since they are pricey, it helps deter me from using them all the time).
