I have a surgery scheduled for 08/25 and I had to do a three week liquid diet the first week I didn't do so well I had some slip ups and this is the start of week 2 how can I keep up with this liquid diet I don't want the surgeon to cancel my surgery and its hard for me to drink 4 protein shakes a day or keep drinking water sometimes I forget to. I just need some help to not mess this chance up.
