Mona Vie Energy Drink and the Lapband

Since my band, I have developed indigestion problems which has made me quit drinking coffee. I have a hard time feeling awake and almost drove off the road the other day going to work..starting investigating energy drinks when a nurse friend of mine talked me out of them. He suggested I try the energy drink put out by Mona Vie. I ordered them and they arrived today.,.in looking at the can it said it was "lightly carbonated" which I didn't know when I ordered it. Has anyone used this beverage and will the light carbonation be a problem for me...I have given up all carbonation...recovered from my Diet Coke addiction..don't want to stretch the band. If anyone has used these drinks...please let me know if it will be an OK solution for me.
