I've been consuming Soylent 2.0 for near 3 months now, averaging 3 bottles a day, sometimes up to 5. Everything's great except I've been having diarrhea fairly often. Not only that, but maybe once every 2 or 3 days, when I have a bottle within about 5 minutes I have a stomach gurgle and it's straight to the bathroom -- it seems to force out whatever I've got in my gut at the time (say, if I had a salad a few hours earlier, that undigested salad is in the bowl), which is a bummer. Overall, the ease of consumption has kept me consuming it, and I'd hoped that this issue would die down as my body got used to it, and although it probably has improved a bit since April, the frequent diarrhea and occasional immediate gut reaction is a pretty big bummer.
I did a bit of googling around and saw that people suggested trying a probiotic supplement. I got a 30 days supply from my local pharmacy and took it every day in May, but it didn't really make a noticeable difference. I've also seen the suggestion of adding fibre (in the form of psyllium husks or other), but I'm thinking that fibre might not necessarily be the issue since I sometimes have quick and violent gut evacuations right after having a bottle as mentioned above. Definitely seems like there's something in it my body's not so big on. I don't have any known food allergies or sensitivities, though.
So, I was wondering if anyone else has had similar issues that they couldn't get past by using probiotics, and if they've had any success. Or if anyone has any suggestions about how to zero in on what might be going on?
