Thank you for your inquiry. I have a few questions for you, for clarification, that will help me respond.

What is your primary diagnosis?  (That is what type of cancer do you have?)

What are the chemotherapy agents that physician is wanting you to continue to take?

What medications did the physician give you to control the nausea and vomiting? The National Cancer Comprehensive Network (NCCN) has identified a standard of practice for managing Chemotherapy Induced Nausea and Vomiting (CINV).  If I know the chemotherapeutic agents you are receiving I can better respond to recommendations for controlling some of the symptoms you are having with the chemotherapy

It is preferred that patients “maintain” their weight during cancer therapy.  Losing over 100 pounds during your three cycles of chemotherapy concerns me.  PLEASE request referral to a dietician in your Center.  There is NO CHARGE for this service and these professionals are well trained to work with you during therapy.

If you lived in California medical marijuana might be considered.  I have heard it is helpful for the nausea/vomiting, as well as other side effects, in some patients.  However, in the State of Texas it might place you in a “legal compromise” situation.  At this time medical marijuana in Texas is not an option that health care practitioners can recommend.  Marinol is an agent from this “family,” that is used for breakthrough CINV.
