So sorry that your nausea is so bad @riss81 - I wonder if you are also having some vertigo? That makes your head spin when you try & stand up ..... it SHOULD settle - can you call your Breast Cancer Nurse? They may have some suggestions .... Definitely ring your Onc and/or the Onc Nurses first thing on Monday morning xx. I hope you have good support at home .....
You should notice a pattern after 2-3 doses ..... When my hubby had his chemo, he was OK for 2-3 days, then on the 4th day, he'd just put himself to bed for 2-3 days .... he'd eat when he felt like it & just slept a lot of the time. Then he'd bounce back. xx
take care & wishing you well
