My slippage was determined after it was removed, i guess they could tell by the placement of it. I was SOOOOO sick for like 4 months prior to removal, I lost almost 40 lbs in that time and not in a good way, I was really dehydrated and losing hair, i looked like a coke whore to be frank! I have gained back almost 60 pounds, I am totally devastated and i am getting married in may, so i want it back in and i want it back for life, i am hoping a smaller band will help, I lost all of my weight pretty quick, the last from being ill, but i need help there is no doubt, i need to lose about 40lbs. and i am doing everything i can on my own.
