My sister had a hard time after about 2 cycles with the pills and OCI. So they switched her to the infusion. It was still rough but not as bad. She was alone at first too so I got our 91 year old mother down there with her to just be there. We also had to bring our cocker spaniel which she keep asking her doctors about a fur buddy. Those little things helped. Now for the nausea this worked try chewing on fresh parsley and if you can ginger tea or even ginger ale.
Good luck and hang in there.
