I've had my balloon for 6 weeks and have lost 18lbs. I'm very happy! I was pretty sick for about 4 days after...I couldn't keep much down, but after 4 days I haven't gotten sick again. I was very weak and had some IV fluids on day 6. I remember on about day 3 it crossed my mind "what have I done". It does get better and your body does adjust. Hang in there that first week. Maybe you will be a lucky one and only have a day or two of throwing up! [emoji4]
