Countdown-Four days down....ten to go! preop diet

Day 4 preop liquid diet done.....I feel antsy like I gotta do something...but oddly not really craving food....I slept an extra hour this morning after the kids got on the bus...I feel weak like my muscles don't want to work...the edges of my vision went wavy after I walked up the stairs and I was shaky so I ate a yogurt. I am good now but weak feeling. Wish I could sleep but I'm not tired. I don't even much feel like fb and that's weird. Wondering how I am going to feel after surgery and if I will adjust to feeling weak and well...not be so dizzy or weak....the dizziness I expected by not the weakness...It's weird...
