Honestly the first day, a Monday, was nuts. I wasnt in pain just not being able to drink until the next day was weird. The toughest thing was getting through the week on clear liquids. I wasnt hungry it was more mind over stomach. Once I got to the weekend all was good. I kept myself busy. Now I'm having trouble but not everyone does. I can't keep anything down and I'm at week three. My doc says everyone progresses differently. There's nothing to be scared of and not much to prepare either. Take it one day at a time and you will do well. I have a friend whose 10 months out has had no problems and is doing wonderful. Don't waste time worrying this is something that in the long run week make thou much more healthy. First nights sleep was the hardest after that each night for better for me. Make sure you ask for the pain meds. Best of luck!
