Hello everybody, my surgery is friday. I have been on the liquid well it will be 4 weeks friday. My doctor decides how many weeks you have to do by your bmi. I have lost 23 pds so far. It has been very difficult, I drink the kroger brand slimfast which is called slim rite. It taste alittle better. I can't wait for this surgery to be over. And can't wait to get thin and healthy!!
