I Have Been Taking Lactifibre From Last 5 Days And

I have been taking lactifibre from last 5 days and it's working really well for me! What i want to know is that i was taking 2 scoops every night and now from today im taking 1 scoop as the problem is solving..... For how more days should i continue it,does it have side effects and does it flushes out all the food?
It was prescibed by the doctor
