KnockOut

So I had my VSG on July 8th. At first things were going fairly well, except that I would violently heave whenever I tried any form of Protein supplement. So I was getting down all my protein normally, etc. although my caloric intake was at about 300 a day and my protein intakeat about 10 grams. WAY too low I know. Then 3 weeks ago everything changed. Badly. My cotton mouth intensified to the point that I was barely able to stand it, and I developed the msot grotesque taste in my mouth that I couldn't nullify with anything. Then I started dryheaving forcefully about 8 times a day, sometimes even before I had eaten anything. I went to my doctor and he said he was confused as to what was wrong with me. He suggested that maybe I'm in severe ketosis and instructed me to add some complex carbs to my diet. So I have. In the last 3 or 4 days the taste has changed. Now it's a sour taste that is equally unbearable. It makes literally EVERYTHING I DRINK, even Water, taste sour, chalky and bitter. I need relief from this NOW. This journey is tough enough without having to deal with this taste. It is literally driving me insane. Please help!
