Last night I was doing some research and discovered that Grapefruit Seed Extract and grapefruit juice can interact with cancer drugs. "Continued use" can reduce the effectiveness of the chemo drugs. I have been taking GSE since the 7th day, with some regularity. I did this out of habit since we do this on most trips to build immunity against everything that travel exposes us to. It does work, but now I will stop using it. The choice: cold or ineffective cancer treatment. I guess I will take cold.
As a result of this discovery I lost sleep last night and have a scratchy throat today. :-(
We leave tomorrow evening.
