Wow thanks @Wildplaces - great info - I hoping the Dex will be enough and I won't need the Maxalon but I'll keep the Zofran in mind. I remember taking metoclopramide to increase my breast milk supply when I had my first baby (23 years ago!) but I've also heard about a correlation between metoclopramide and parkinson's disease, which my mum had, so I'd prefer not to take it if I can avoid it.
I'll absolutely look into the Lumergan! Is it true that eyebrows and eyelashes are the last to go? Or do they fall out straight away?
