Preop diet

So my surgery is scheduled for March 13th and I’m very nervous but excited and ready to get the surgery over with and their were still some people whom were trying to discourage me from getting the surgery but have since excepted it because they know I’m trying to get healthy and their were those whom looked at it as cheating by getting the surgery because they don’t see it as a tool but if they were to be in my shoes the past year up until now they might change their mind this isn’t easy I started my pre-op 2 week liquid and it’s been very tough I’ve notice my energy has been low I’ve been getting headaches and have been feeling hangry aka hungry+angry because I see everyone around me eating food and I’m on a strict liquid diet I then realized that I was only taking in half of my calories a day so I have to increase my calorie intake a lil and increase my protein shakes grams to curb my hunger it’s been very difficult an although tempted to eat regular food my willpower has been kicking in but this is hard those who aren’t going through this whole process don’t know the amount of sacrifice,hard work,and dedication it takes to do this but I’ve just been continuing on my journey if anyone has advice on the best preop liquid diet to reach 800 calories leave a comment I’m trying to do things right
