I like the product and the idea but I become incredible flatulent when using queal and the consistency of my stool changes. (It's the same with joylent). This is fine when I'm home but when I'm out this leads to cramps and I need to find a toilet hourly. If I eat only one bar a day the effects are minimal. However it is quiet difficult to impossible to use the product. I don't know if this is the cause of not but when I eat sou beans I have similar syntomps.
