Naked Boosted Green Machine Juice

I tried this juice at Costco couple of days ago and I liked it, so I bought the 64oz bottle for $5.99. This juice taste very good: no nasty grass flavor with no sweetness to it; it tastes of about 90% fruits and 10% vegetables, but generally its pretty much a multifruit juice. I drinked the whole 64oz bottle in less than 2 hours, but then 5-6 hours later I began having the "runs" [2 of them] to the bathroom.
