Hi! nice to have you here. I've heard a lot of pros and cons about the balloon - so it'll be real interesting to follow your experiences. i guess one of the reasons it's not popular in the US is because it is meant to be removed - and the assumption is that people will regain their weight.
what have they told you about what happens after the balloon is removed? and i gotta say - based on your description, i'm wondering how it FEELS in there!!!!
inquiring minds want to know!!! BTW - why did you choose Prague? is there someone in Kent who can do your followup? will you go back to Prague for the removal?
