Hopefully your Mum will skeep better once of the dexamethasone. I found I never slept the day before or a couple of days after it properly. Just spent my days dozing. But the dexamethasone really helped the nausea, mine was extended to 4 days at reducing doses. Made a huge difference. I also took stemitil and ondasetron. The stemitil regularly and the ondasetron 1/2 before meals. Seems a lot but it worked. Maxalon made me restless. I alsi foubd a trick with the ondasetron, I'd put a sugarless mint on my tongue before I put the wafer as I detested the taste...but it was extremly effective. Keep up the salt water mouth washes and hope the next round is kinder. Kath x
