Yes, I was 17 years old. I am now 28. I was 310, got down to 195 and maintained that weight for quite some time. Within the last 2 years I've put on some weight and am at 235. I had the Roux en Y operation. I had a severe iron deficiency and have recently gone through IV iron treatments. I take a double dose of B12, Vitamin C, Fiber, and Multivitamin every single day.
