Hi all. I'm new to the forum and my surgery date is April 15 for the sleeve. I was put on a 21 day pre op diet of 2 shakes and one high protein meal a day plus clear liquids. I started Friday and it has been rough. The first day I had major hunger and nothing seemed to fill me up until supper when I had whole food. Saturday was worse because my stomach was totally empty in the morning which brought on nausea and vomiting/dry heaves. That has happened to me in the past when I have had an empty stomach and took my dog for a walk. Today was the same wretching mid-morning and feeling nauseated all day. 

I am am calling my team tomorrow to tell them. I don't know what my deal is but it has to solve itself soon. After April 6 until the 14th I can only have shakes and clear liquids.  Any advice?
