Baffling Stomach Illness - Need input/suggestions-I am tryi

Hi Kitten

Have you had any barium meal tests??? This is where you have to drink some liquid then have x rays to show up the digestive system?? I am trying to figure out on my own what is wrong with my stomach these last 2 years (at least).

My symptoms include:
Stomach pains
Constant vomiting during an attack - specially in the morning and whenever i eat or attempt to drink (even a tiny drop made me gag)
Increase in fatigue/lethargicy
Big increase in thirst
Diariah (70% of time) /Constipation Yo-Yo'ing
Attacks lasting 1 day to a 9 months
Decrease in what im able to consume in my daily life (also during attack)
- Lactose intollerant (constant)
- Meats make my stomach hurt (constant)
- Sugar makes my blood sugar all goofy when i do consume enough of it at one time (constant)
- Liquids/Soups make me very queasy including drinking anything (during attack)
-Spices upset my stomach

I have been hospitalized 2 times for IV fluids during these and have had to go in 3x a day for a full week to get injections of anti-nausea meds because i couldnt keep my normal meds down or the A-N one.

I have to admit i HAVE been researching some on the internet and have only come up with a few options at best. Wich are either IBS or CVS (Cyclic Vomiting Syndrome). I have been to a GastroIntologist (i duno if thats the propper name) and ALL tests have come back negative including the camera down the throat to see if anything was up, barium meal tests, ultrasound of abdomin, CT scan of abdomin and pelvic area (both with and without contrast). So i am very confused and tired of this
