I started my liquid pre-op diet on Monday morning. I've dropped 7 lbs in 2 days! I have followed the diet as directed and I'm getting in all of my protein and clear fluids... But, I am feeling somewhat weak and shaky, especially in the morning time. Yesterday, it subsided once I had a protein shake and some sugar free jello. It is the same today. Just curious, does anyone else experience weakness and shakiness while on the pre-op liquid diet?
