I felt tired and exhausted, couldn't walk to the end of the street, I wouldn't have wanted to walk the streets of Paris, or trekked the Himalayas BUT a holiday lazing about on a beach would have been a real delight. By the end of rads I had my sense of taste back, too. I say go for it!!!!!!!!!!!!!!!!!!!!!!!
There is a travel insurance thread, you might look at it for advice. You
can get insurance that covers stuff not cancer-related, and it may be worth ringing round to find out what's what--companies that are willing to work with you are named.
