Welcome to autumnleaves and shouldidoitspoilt.
shouldidoitspoilt This is belated, but if you suffered badly last time, definitely you should have for pre-emptive meds. Which meds helped last time, if any? As you are a veteran, you don't need my spiel about 'full sugar, flat coke and ice lollies and the juice of tinned fruit and have you got kesostix? ' Did you find an anti acid helpful last time?
autumnleaves Sorry things are getting worse. Cyclzine does make most people sufferers initially, but most get used to it. If it isn't helping a lot, do ask for something a little stronger, like stemetil. An anti acid can make a big difference. Some liquids 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) 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.
eallison Congratulations on that productive meeting at work (I think you said you are a teacher?). Much sympathy over horrible journey home complete with puke at MIL's. I am glad you had a nice booking in.
elpreggo I hope the hot dogs and kethup stayed put.
MotherofPearl Lovely to hear from you. I hope LO's are thriving? Thank you, and thanks for lovely supported message. 
Reastie Some doctors prescribe meto. long term, but others are cautious about it, not through any threat to the baby,but because it can make the mother twitchy,and if so, must be discontinued. For that reason some doctors are wary of prescribing it long term. What does your GP say? I am glad you have got an increased dose of Ondansetron. It's infuriating about the red tape in prescribing.
Mamabear I am so glad that you are coping. Always lovely to hear from you.
SeaEagleFeather I think you have a great memory.
beanhunter I hope you don't feel too bad.
