I had pretty severe hyperemesis but was also shamefully stubborn when it came to treatment. I was given 24 hours before I had to go to hospital. At that point even a sip of water would not stay down - or even just trying to move a short distance made me violently sick. I think alot of that was to do with the fact that it was affecting my blood sugar which made me very tetchy and quite confused at times. The symptoms reminded me of a particularly severe hypoglycaemic attack I had had in the past. By utter accident (and maybe it is completely coincidental) I discovered that self-medicating with a glass of coca cola (which I normally hate) was like a miracle cure - therefore leading me to believe that it was more my plummeting blood sugar caused by rampant hormones that was exacerbating the constant sickness. Maybe it's just my body's little clutch of idiosyncracies but I can thoroghly recommend a boost of liquid sugar to make you feel normal again. Needless to say all the vomiting recurred much later on with severe cholestasis so I guess all along I must have had a difficulty processing all the hormones. Thankfully, everything was ok although I have decided not to go through it again for all the above reasons!
