Hi... I am new....I am about to have the gastric Bypass with the band

I am nervous, scared and excited....I am a big big girl....Probably need plastic surgery afterward. I am looking forward to a new life....
I need all the help you would like to share with me.
What's the best protien?
best vitamin?
I am going to go and do some reading, to see what I can come up with.
Has anyone had to have plastic surgery?
Time is short for me right now, will check in later.....I am thankfull I have a place to go where people can relate....
