l_mahnesmith,
My surgery date is September 8th. My surgeon only required one week of the liver shrinking diet (thank goodness) and I started that today, in the middle of a holiday. To combat the headaches and overall tired feeling, try bouillion (spelling) cubes dissolved in water. Don't ask me why they work but they do. I forgot mine today and I am not feeling my best. But in the end it will all be worth this particular period. Hopefully someone else will chime in with how they managed through this part. I need the motivation too.
Good luck and let us know how you are doing. You are almost there!
