Dont beat up on your self, this is my second time around , meaning my first attempt at surgery was halted no fault of my own just a unknown issue situs inversus, so ive been on this journey for a little over a year, went back to my 9old habits quickly, but gets better, im on my pre op diet and had a slip up nothing outrageous so just keep pushing forward i too had the second thoughts even with a week until my surgery, but i think of the health benefits in the end.
