I'm home
Hey Lisa:
Welcome to the losers bench. When i first got home, i had a hard time with liquids as I had a habit of gulping. A straw really helps curb that and I still use once in a while. It is possible you have a headache from dehydration. Just make sure to sip and walk around your house a little to help avoid blood clots. Think all of that is as important as the surgery.
Take care and keep us posted on your progress,
Pam
