questabella Really sorry you are still in hospital. I so agree with bored and others, it's well worth asking a doctor if it's thought the best thing.
Sabulous Glad that you are having a better day. It is unlucky that the bad pregnancy sickness you had last time has turned to Hyperemesis this time. You might find the list helpful, as fizzy sweet drinks seem to help a lot of people. The infamous flat full sugar coke, the juice of tinned fruit, Elderflower Water, ice lollies, soda water, fizzy orange, orange squash, Lucoazade, sips of chocolate milkshake, Dr Pepper, lemonade, ice cubes and Robinson's fruit drinks. For solids, tinned fruit, Scotch pancakes, nibbles of chips and crisps, cheap ice cream, slices of melon and mango, cornflakes and jelly. It is certainly worth while buying some kesostix from a chemists to check for early dehydration as hospitals take the readings from those seriously.
hotchocolate Is it impossible to manage without a return for work? As usual, Mother Hen says don't rush back, as it is no good returning when not fit for it, and having to be signed off again.
bored and seize and everyone - great advice as ever.
