Ugh-ly way to lose weight

I'm so tired of being ill. It seems like it is always one thing or another. This past six weeks or so has been digestive issues. I have lost several pounds and am consistently in the low 190s, dependent on swelling.  The problem is that I've lost it by being nauseated a lot of the time, actually vomiting once or twice a week. Two Sundays ago I was so ill I couldn't even keep down my ginger ale. I ended up calling Debbie and asking her to take me to Urgent Care. They gave me a shot of phenergan to immediately stop the nausea. They also gave a prescription in pill form. I've only taken it once. The info (and commentary) states it will cause extreme drowsiness. It didn't seem to do that for me. I slept after I took it, but had extreme nightmares. I have an appt in June to see a GI doctor. Until today I had secretly planned to cancel it. Today, however I went back to nothing sounding good to eat. Finally I thought mashed potatoes sounded good. I made some and ate them and one and a half small sausage patties I had cooked to freeze for future ease.  I've been feeling disgusting ever sense. All I have consumed today is one can of Sprite, one small packet of fruit snacks, a gluten free ginger cookie and the above mentioned. Even typing about it makes me feel sicker. Ugh.
