Hi Glasgow Girl,
Yes you can do this, your mind is fighting not your body.
I had mine out last saturday at 10am,so can speak from experience really.
I went on soups and soft foods ie yaoghurt smoothies day 1 of 3 moved then to clear soups liquidises took 2 laxatives to clear my stomach on day 2.
Day 3 slim fast or similar dont do what i did have chocolate as food in the stomach comes up when they removed ballon ,mine sprayed all over Doctor and he was smiling whilst i was gagging(find it funny myself now).
Dont forget the coke for final clean of ballon that night leave 12 hours between last drink.
I was up and at Manchester U.K at 11.30am shopping with no ill effects .
Good luck( no Meds or antisetic for removal my choice)
Slightly sore throat after but nothing to complain about
Over 3 stones gone at goal and toning up at the ripe age of 53.
Following G.L food plan 80 % of time in future lost 3ib after ballon out,so they you go another plus.
Gloria
