I did not have to do the sleep studies, however it did take me a longer than 2 months to get this all done. I had to see my family doc for 6 months straight, loose weight to get to a bmi of btwn 45 and 50, get a psychiatric consult, see the dietician 2 times and have a nurse teaching session. In all it took me 7 months. I am scheduled to be banded on 9-8-08. Good luck to you!
