Jlw2020 Sorry, how rude of me. I forgot to say what a nice scan picutre that is.
Nam095 I so agree with others, it sounds as if you are dehydrated and need your urine testing asap to see if you need fluids. As Stemetil doesn't seem to be helping you, there are other meds they can try, and combinations. Most sufferers find that they improve a lot at some point between weeks 14 and 20. Even those who are unlucky enough to suffer throughout generally are not as ill later on as they are in the first part. A good anti acid can make a surprising difference to the sickness. Kesostix are worth buying online or from a chemists, as while they aren't they best test of dehydration, hospitals take them seriously. Some drinks that have helped others: full sugar flat coke, ice lollies, the juice of tinned fruit, Lucozade, apple juice, Ribina, Dr Pepper, soda water, Elderflower water, tonic water, ice cubes, Iron Bru, lemonade, lemon squash, orange squash, orange juice (if not too acid), fizzy orange, 7Up, isotonic drinks, sips of chocolate milkshake (maybe soya), fizzy water, apple juice, Robinson's fruit drinks, Rubicon sparkling mango drink , raspberry Lucozade sport and frozen ice cubes of flat Lucozade sport . Foods of a sort include tinned fruit, cuppa soup, nibbles of crisps and chips, cheap ice cream, Scotch pancakes, bagels and biscuits.
greatgreengrapes Good suggestions from you and everyone about drinks.
Wingingitatlfiesincebirth I hope you find some drinks from the suggestions that help you.
LadyPenelope I so agree about Lucozade or Lucozade sport. It is miserable existing on a bit of breakfast, and not always that. I hope it eases for you soon. Several sufferers on here have been prescribed Metaclopramide along with Ondansetron.

That was unpleasant about the Metaclopramide.
Snapple21 It looks as if kalidasa's advice about steroids to SweetpeaorMarigold and others might be very relevant to you by the sound of it. Very useful that her father was a doctor and not anxious about the use of steroids.
