islet cell transplant/pancreas transplant

I have type 1 diabetes which is badly controlled although i am doing all i can to keep my blood sugar stable. I recently saw a consultant at manchester royal infirmary to discuss options with regards to me having islet cell transplantation or possibly a pancreas transplant as i am taking a lot of insulin for my body mass and islet cell might not be suitable. Has anyone undergone either of these procedures or currently having appointments to discuss options as well? I would be interested to hear other peoples experiences to enable me to furthur weigh up the pros and cons.
Thank you for your time.

Thank you very much for replying, i will definitely take a look at your blog. I think it is so much more helpful to get the opinions of someone who is in the same position as yourself than listening to a doctor try to tell you everything. Any extra info i can get to help me make an informed and positive decision is much appreciated.
