I  am scheduled for surgery this Friday.  I have been reading as much information as I can in order to see how I can be a success as i enter this new chapter in my life.  I am so fortunate that my husband is so supportive; so supportive in fact, that he said to do it even if insurance didn't pay for it, we would pay.  I have been on the pre-op diet for about 3 weeks with 2 shakes a day and 1 meal (usually at lunch time) and after the first week, I found that I was not looking for food all the time.  I have also recognized the fact that if I am not hungry, I don't need to eat.  I hope this willl continue right on through my recovery phase. 
 
Can anyone tell me what type of protein drink you used during your liquid stage?  I am not quite sure if I should stick with the one I have been using or go to something else.  I am currently using EAS advantEDGE.  Any advice?
 
Also, have any of you had problems with light headedness after surgery when you aren't really eating anything?  I don't want to fall over and embarass myself.
