I was banded Aug 9 and there was no way I could have went back to work the next day. I was to go home the same day but my doctor wanted me to stay overnight. The 1st 2 days I was in bed and got up to drink and try to walk out the gas. You MUST give your body time to heal or you could have issues with your band. Do you have a TA to can do the class or have another teacher do the two classes. Good luck.
