Hey, I can understand your fears about everything. I was sleeved by Dr. Aceves past November 2009. I remember the fears. Let me reassure you that Dr. Aceves and his team are wonderful. I felt that this was the first time that I was treated with so much respect by a doctor. He listen, he understood and he answered all of my questions. Dr. Aceves is a very gentle man with a warm personality. He has a wonderful sense of humor. His staff are just as great. The hospital is very nice, very clean, a pleasant atmosphere. My husband accompanied me and he was very impressed. You will have tests done the day before surgery. You will have an ECG, blood work, Urineology test and a chest x-ray. The results will be discussed with you. You will meet Dr. Aceves prior to surgery. You will also meet the doctor who does the Aneistetic (forgive my spelling). You will in fact see Dr. Aceves many times throughout your stay at the hospital. The nurses are great, I did not find much of a language barrier. I wish I could reassure you more, but trust me, once you see the hospital and meet Dr. Aceves all will be well. If you have any questions please dont hesitate to contact me. *chin up..hugs*
