I second what Aimee said 're taking each day as it comes and enjoying. Try not to worry too much - inevitable I know, but there is nothing you can do to make things stick, it's In the hands of whatever.
But positive thinking has to be a major help. I know it sounds daft but I honestly thought that my dead grandpa was up there helping this one stick for me. I just had that feeling it'd work, prepared for the worst, but just felt positive it'd work..... can't explain it to be honest and never really told anyone before, but just knew my grandpa was helping me along!!! That and having two weeks off during and after the process from work!!
Whatever helps you keep the positive thoughts will help!!!!
