I completely understand how you feel, my advice is to just research & read all you can on it. Then do what you feel is right for you. Surgery isn't for everyone. I am scheduled for lap band on Nov.25th, just went to my dietician appt., which was quite an awakening. No food in the beginning, pretty much liquids & baby style food....LOL!
I started to ask myself do I really wanna do this? But, I know I will benefit in the long run from it all, & will be able to eat normal food eventually - just in proper portions.
Good luck & God bless!
