I am SO sorry you are experiencing this. I fought an AWFUL battle with nausea last weekend. One thing I forgot to try was a dose of dramamine. This does work for me - when I can remember it!
I don't advocate eating as usually when I'm super nauseated, it just comes back up :( Sometimes a salty something helps...
Also, when are you taking your Imuran? There has been lots of talk - and trial and error - here about
taking it in the evening before bed to combat nausea symptoms.
I hope something works for you! I completely empathize...
