I had a friend who went through with the procedure a few years ago tell me what helped her was taking a picture of herself in the same pose every two weeks her entire journey. She kept the images in one folder and set them up as a slide show as her screen saver after reaching her half way mark. Because she saw the changes every single damn (basically bombarded with the images) her brain saw and acknowledged the change so when she was at her goal weight the slimmer and healthy her was someone she knew well and accepted.
