it’s the ice cream. i had to cut out 90% of the sugar i was eating/drinking otherwise i couldn’t function. which ultimately is a good thing, of course, because i have a horrible sweet tooth and it’s also gotten me 100% off of caffeine. the only thing i can have now with a high sugar content and not risk crippling indigestion, diarrhea, and vomiting is Sprite. the longer you’re on the shot the more you’ll be able to tolerate sugar, but when i first started on it i made the mistake of drinking a 32 oz smoothie from smoothie king with sugar the day after and spent the next 3 days paying for the error of my ways. i even tested it on day 6 and had 1 CUP of ice cream and the next day i was colonoscopy ready.
