I think I did that thing when you start a conversation in your head and then your comment posted mid-thought has no context, iykwim?! What I was thinking was: Feeling nauseated can reduce your appetite, as can repeated vomiting and the anxiety associated with it. People with chronic nausea tend not to want to eat, and not eating (or vomiting what you eat) is far more medically problematic than experiencing nausea. Hence, stimulating appetite as well as suppressing nausea is what makes medical cannabis so useful for cancer patients. But OPs wife isn’t going to see the anti nausea/increased appetite side effects from CBD alone. THC is the more important cannabinoid, and if she’s no longer pregnant/breast feeding she shouldn’t have a problem getting it prescribed- even in the UK. But it will be a private prescription here which is expensive af.
