We've only used this once, but it kept us awake most of the night.  We were surprised because it's decaf, but we couldn't sleep for hours after going to bed.  Tastes good, though.

Ex Input:
In all fairness my friend absolutely loves this product.  I purchased it based upon his suggestion.  Unfortunately, the smell (oil I am assuming) of it cooking made me feel ill.  Even though the product cooked perfectly, the smell lingered in my microwave for well over a day.

Ex Input:
Check out the nutritional info, the SODIUM: 5,510 grams! 230% of your daily requirement. I used this and our casserole was ruined because it was so salty!!!!!! And what's up with that price? My box cost a dollar. Unfortunately I bought two boxes, so I'm throwing the other box away. No bargain here. It is wildly UN-delicious and UN-healthy for you! (Yeah, I'm embarrassed that I didn't read the label first!)
