Hope you're sleeping soundly...west coast time at 11pm here. I brought a few extra squishy pillows from home and was so glad I did!!! You might want to get a list going for comfort and boredom....deck of cards, smuggled in foods (NO fast food....too salty!!!!), magazines, taped music, etc. etc..
Waiting is hard no matter where you are. I am glad they are being careful with you and that your doctors are all very attentive. If they say the fluids will no longer be a problem after your surgery, then believe them. Optimism and a positive outlook can really help you breeze through this. It is hard to stay in that good frame of mind, but you must work to keep yourself smiling with the nurses, hugging your family and friends, laughing at jokes. Keep your eyes and ears out for the silver lining in everything right now. So many of us have weathered those last few days to make it over to the good side of things. It really will be fine.
Write as much as you like! We're here for you. We know it's tough. We understand completely!!
Best wishes.
