Mother yes he definitely was nasty, DH felt he was insinuating that I was being irresponsible. Really interesting to hear about your conversation with an A&E consultant. I actually had a long talk with the GP yesterday because he said he'd rather I was off the ondansetron and just taking cyclizine before I go back to work, which obviously led me to ask if he thought ondansetron was dangerous. He was very reassuring and said he was confident that I was taking 'safe' meds, but ondansetron is quite strong, so he'd rather I was off it and demonstrating that I'm coping 'on my own' rather than risk going back to work and getting worse again, and then having limited options for medication.
squeezed if one more person offers me ginger.... I know that medication isn't ideal, but I also know that women in America are often offered it as an intervention earlier than in the UK. I refuse to suffer just because of where I live, and dehydration is so dangerous anyway, I'm so much better off medicated and being able to drink and eat than in hospital with my ketones off the scale.
Got everything crossed that things start moving for you soon squeezed.
Special sorry you've had the 'confrontational pharmacist' issue too. I'm so glad that I got the ondansetron and didn't have to wait until my GP opened on Tuesday- I don't know how I would've coped. Like you say, it's not the questioning that's the issue, it's the way it's done. Making my husband feel like a criminal does no good to anyone! He would've been more forthcoming with information if the pharmacist hadn't been so aggressive, we would've happily shown my hospital discharge letter, etc. But he didn't even ask about my condition, just kept parroting the "extreme cases" line even after DH had told him it was prescribed after a hospital admission. If I'd been there I would've been really upset so it's just as well I'm stuck in bed at the moment. Although maybe if I vomited on him he might have believed how "extreme" my condition is 
Thinking back, the consultant did warn me that primary care professionals can sometimes be a bit anti- ondansetron, but because my GP surgery have been so supportive (literally every member of staff from receptionists through to doctors), I hadn't given it a second thought. Lesson learned. In other news, my Dad is desperate to collect my next prescription for me after I told him what had happened, but I think it's just because he's so wound up about how ill I am that he'd like an opportunity to shout at someone in my behalf. He keeps looking at me sadly and saying things like "they didn't leave Kate Middleton in this state did they?!" Erm, I think they probably did Dad...
bless him.
Glad to hear that you're feeling that things are more controlled mrsmonkey. If you find something that works for the thirst, let me know!
