I've been on this stuff as a stand alone for 5 days and feel like absolute ****. This stuff has made me feel hypoglycemic as hell (no I'm not diabetic), so I upped calories with no real help. It has made me exhuasted and nauseous as well. Not sure what's up with it as I had read some decent reviews. At this point, I have no choice but to stop taking the product, and I do feel obligated to warn others as I feel it's a waste of money and perhaps dangerous.
