We got our Soylent yesterday and my wife and I both made a batch and drank a cup. About 30min to an hour I started getting a weird buzz (like taking too much day cold medicine or being over caffeinated) that my wife also experienced which she described as an oddly anxious feeling, this led to massive headache that lasted for both my wife and I the rest of the day. Today, I’ve had stomach pains and gas throughout the day my wife is also complaining that she still doesn’t feel right. We only had one glass each and we only had our normal morning coffee to go with it and didn’t eat anything else before we both started feeling ill.
I know this isn’t just the fiber in the product as my wife and I normally supplement our diets with extra fiber like psyllium husks. Plus we didn’t go cold turkey on other food and just only eat Soylent for several days, we just had one glass each.
We normally eat an organic diet so I know we aren’t used to the processing in these ingredients, but I have many other shake products, many with high fiber, and I’ve never had such a bad reaction.
It is just disappointing, I have a busy job and having something that would be a quick nutritious meal would be great. I don’t know why other people put up with toughing it out, I can’t really think of a food product that has ever given me a reaction like this except maybe something that went bad.
