About a year ago, I tried a sugar substitute for the first time, Swerve Confectioners, to add to my carafe of lime or lemon water when I craved lemonade or limeade. When I ran out last week, I bought a different brand without reading either ingredients list. I used the new erythritol sweetener in my hot chocolate today - big mistake - it didn't sweeten and I ran to the bathroom about 45 minutes later. I get that same effect when I juice any fruits other than lemon, lime, or apple into my veg juice. I assume I'm sensitive to the sugar alcohols. When I get the chance, I will do some research on fructooligosacharides vs oligosacharides.

Anyone else have these side effects? Any food scientists out there?
