eating pasta after taking laxatives

i feel like such an idiot. i did the fecal impaction regime (8 sachets within 6 hours) and had the niagra falls come out my bum. but then later for dinner, i had some pasta, it was quite a lot of pasta. and today havent been to the toilet once. im worried ive made myself constipated again. for fuck sake. im so angry. why did i eat that pasta for fuck sake
