Mar,
So sorry to hear Alan's having such a tough time. The PEG will help a lot. Unfortunately Carnation VHC is not available in Canada. If you go to Shoppers Drug Mart, or Walmart pharmacy and order Resource 2.0 it has just as many calories, and is really easy to tolerate compared to a lot of the other preparations around.
Make sure though that they order Resource 2.0 and not resource plus. the 2.0 has a much higher calorie count. I spent almost 5 months living on nothing but Resource...it's good stuff.
Is your trip in July back to the Tom Baker?
