I completely understand your fears.
I have just decided this week that I want to start this journey. I have always said I wouldn't do it while my kids were small because "what if" something happened. Well, "something" is going to happen if I don't do it!
I had never heard of VSG until I started researching and it seems like an appealing option. EXCEPT when I realize they are taking my stomach FOREVER! But then when I put in the con's list...the pro's are going to win every time.
I am realizing I have some mental issues right now because I keep thinking that I am going to miss "food". I know that sounds sad but I am sure I am not the only one who has thought that.
Good luck to you. Find peace in the words of others who have had this surgery without complaints. Remember all the "Pros" on your list.
