Hi there Tigard!
The pepsi has got to go! Won't work with the band. Make it a pre-condition for her surgery, if she can't quit the soda, she won't have the discipline to follow the band rules.
Good!
The only problem I had was gas pain in my shoulders as expected but that was manageable and gone by day 2.
There is a thread of surgery day stories on the forum that has tons of details if you want to look for it.
There used to be a guy...scratch that genius, who conducted a scientific poll on this very subject. His name was Dan and he was somewhat of a hero of mine as well as for thousands of others on the forum. Check the wisdom here ....
