I am SO glad you can laugh about the 'name' association, @Number2
The 'medical team' we refer to is usually the Surgeon, Rad Onc and Medical Onc ..... so if you can contact your Medical Onc on Monday (who is in charge of your chemo regime) and explain just how badly it is affecting you - you may be able to get the dose adjusted .... or maybe increase the dose of gastrostop (or try a different one?)
I didn't have a BC Nurse either 'as such' ... so never relied on one. You really need to advocate for yourself ... and that is why, I reckon you should contact your Onc on Monday xx
I hope you can get on top of the gastro xx
