Do i have to wait 30mins after takin the HydroxyCut Advanced Drink Mix? wat if i cant some tyms? will it work?

i just started it today and im taking the 3 packets a day like the HydroxyCut Advanced Drink Mix, Wildberry 21 packets box said to. the thing is since im going to school full time my schedule interferes with my meals lol im able to drink the 3 bottles of course its just sometimes i cant wait the whole 30mins to than eat cuz by that time, i may need to be in class already due to my small breaks in between my classes. i just want to make sure by me not waiting that it doesnt effect my weight loss if anyone could let me know id really appriecate it :) thank you
