It's day 7 and its been fine. I've done 5 days of full liquids and now I'm on the second day of clear liquids. I haven't even been that hungry and I haven't felt like I was going to die.....until this afternoon. I am so nauseous that I can't even hold Water down. What's up? Has that happened to anyone else? Does anyone have any suggestions or fixes?

Yeah, so you're probably too deep in ketosis. Are you drinking any clear protein drinks like Isopure? Or only drinking broth? If it were me, I'd try to go buy prepared popsicles. Even though you buy the sugar free ones, I think they still have carbs and that might be enough to lessen the depth of the ketosis. Deep ketosis makes you SNATT (semi nauseous all the time) lol. Congrats on your coming surgery!!!
