making a tea with slightly acidic not-too-hot water helps quite a lot

also chewing fresh ginger or ginger tea

starting on an empty stomach, of course

but surprisingly, sometimes a little bit of miso soup midway can help with the "gastroparesis" type nausea that can emerge late stage

and also a little bit of diphenhydramine if it's still bad (like less than an antihistamine dose)

even if it is all kind of lipstick on a pig :)
