surgery date

I have just received a surgery date of may 8, 06. i go for pre op tests on may 3. dr syn will be doing my surgery, i am so excited but a little nervous all at the same time, i have had so many people tell me i should not have this wls, i feel i have made a good decision on going ahead and having it, can anyone tell me what i should expect at pre op's and anything else about the day before surgey and when should i go for admission to the hospital, like the night before, early morning or what, i guess i could wait and ask dr syn at my appt on may 3, but i am so excited, i can not believe i am finally going to have this done. rck.
