I'm sorry to hear that the smell came back. but it make sense cause you ate a lot of junk foods in one time. you need to let your body adjust and introduce new foods one at a time and see what's good for and what's not.
did you left your initial diet with the probiotics, milk thistle, psyllium seed and laxatives?
if it helped you once for over a week it should probably work again, just keep sticking to your diet. don't give up, i think you are on the right track! good luck and keep us posted.
