Been a subscriber for awhile... Soylent making me sick now...

So I have been drinking a Soylent (Coffiest) every other day for a few months until about a week or two ago. If I drink even a little of one now I have to immediately go to the bathroom...

... Did I drink too many of these? What's going on here. I love these things. How do I make my body tolerant again? Is this normal? I have tried to stop drinking for over a week...
