Hi Hazed, welcome to the site, dont worry about making your mind up about surgery your surgeon will point you in the right direction. I'm also pre op I've been waiting since March 2009 which is when I went to see my G.P about WLS, and last year around September I started seeing dieticians, physologists, I've just finished group sessions I now have a appointment in May to find out if I have met the critiria to be put forward for surgery, I have no finger nails left i would chew my toe nails but my belly gets in the way rofl.....
