Four new sufferers - goodness. Welcome to MsReader MauisLeftNipple, Lisaloo and JD Duncan. You have had great advice already, about meds and the need for time off work and rest (and for OH''s to try and be understanding!) I can only add, things do get much better for most people at some point between 14 and 21 weeks, and even for those who are unlucky enough to suffer throughout, it is almost never as bad as in the early days. An effective anti acid can make a huge difference,as I hope Reastie will find.
Some fluids that have helped others: Full sugar flat coke, ice cubes, ice lollies, the juice of tinned fruit, Dr Pepper, Iron Bru, Robinson's fruit drinks,sips of chocolate milkshake (maybe soya), Lucoazade, soda water, fizzy water, fizzy orange, orange squash, orange juice (if not too acid) Elderflower water, Elderflower cordial and tonic water and lemonade.
Some foods of a sort, cuppa soup, tinned fruit, cheap ice cream, nibbles of crisps and chips, slices of melon and mango, baked potato and Scotch pancakes.
SilversplodgeI was wondering how you were. Goodness; that sounds dreadful. What stress you must have had. Hugs on offer, if required. I knew you had a threatnened prolapse, I seem to have missed the problem with the growth. Do keep us informed about how things are going.
Olivecake and eallison Great words of wisdom, as ever . 
Reastie I hope Ranitidine helps.
Apologies to anyone rudely overlooked.
