bowel preparation
"By far the best prep yet. No headache this time but I've learned some tricks since. First, it needs to be cold! Drink through a straw at the back of your mouth and chase with water. Took awhile but cleaned me out good. Also, sucking on a lemon after every few drinks. I have a strong gag reflex so had to stand over a sink and focus. I don't drink Gatorade because of food coloring, etc. but Smartwater has minerals in it and drinking a large bottle of that helped keep the headache away. You'd think with all the water you're drinking you wouldn't get dehydrated, but you need the electrolytes that the prep depletes."
