You're drinking only fluids and thea lax tea softens the stools so expect your bowel movements to be quite loose. At a later point the solid stuff will cease and you'll prolly only get the now famous "butt pee" ;+D About the noisy stuff weeeell just think of it as a festive ocassion and get your party hat on.....;+D
If you had 5 movements with just the night lax tea I would say that you did fine by not taking the morning tea and just doing the night tea might be all your system needs to get the poop out. You gonna hafta experiment a little till you find what works best for you. Do consider doing the SWF (Salt-Water-Flush) cause it is a very efficient way to cleanse/flush the whole GI tract top to bottom.
You did the right thing for the headache by drinking lots of water and ade. On my MCs the minute I felt a headache coming on I'd guzzle a whole quart of H2O and it worked everytime.
