So I am now 3 days out of surgery. I still have not had any gas/shoulder pain but I did get a fair bit of wind pain yesterday. It seems to have passed (mind the pun) now though. I'm not having any difficulty with the liquid diet and I've already lost 2kg since Thursday morning. WOW. My breath smells like a camel has been camping out in my mouth from the ketosis, so I've been brushing my teeth like 5 times a day.
I woke up this morning at 4am feeling starving hungry. I was actually getting tummy pains and my stomach was growling so loudly, so I got up and had a few sips of some protein shake I had in the fridge. It worked a treat.
