my experience.
hi, i went to mine in march and can only tell you what was done in mine. I'm at kings college in London.
it was a presentation given from the surgeon telling you every procedure and everything you need to know about it, your expected weight loss, pros and cons. and what's best for different type of people. we were given all the information written too. we got weighed and told our bmi. (wasn't a happy bunny :/)
if your not sure on what you want then this will really make your mind up for you.
Afterwards we were asked to sign if we wanted a follow up appointment and within a month i got mine but Is different in each area.
good luck!
