I had my visit to neurosurgeon yesterday and he has put me on his list for surgery. He says how much weight I loose is up to me but the more I loose the better my outcomes will be. He said there is nothing stopping me walking 3-4 hours a day and reducing my food intake to a minimum. The more I loose the easier the surgery will be and the greater the chance of minimising the risks. I have lost 71b so far so let's see how low we can get. Not sure how long I have before surgery .
