I was on an insulin pump for about 4 yrs. before my surgery, but I have not been on it since the surgery. I was taking about 35 units a day but it was the U-500 Regular insulin (5 times stronger than regular R insulin). I am now taking maybe 2 units a day. Of course I do not mind you asking questions that is what we are all here for! If I can help you through this process at all, just ask!!! I was so nervous before my surgery and I would love to help you any way I can. Once you get your surgery date it goes by quicker than you would think! My surgeon asked me to take my pod off before surgery, but after surgery my sugar shot up to 450. My advice to you would be to take extra pump supplies in case you need to put a pod in after surgery for a short while. I did not take extra supplies and I was 2 hours away from home. I had cotton mouth soooo bad and you cannot chug Water after your surgery...only ice chips and very few of those. It took them a long time to get my sugar down and I was miserable until they did. Now, hopefully I haven't talked your ear off....lol. Good luck and keep me posted with your surgery date.
