Hey John,
Your distances never cease to amaze me, 750 miles is almost the length of our Country! 30 miles destroys me. To think we once Ruled the World.
As for costs, you are worth far more than the arbitrary Dollar value put on your drugs by some Multi-National Pharmaceutical, at least we have the much-maligned but truly wonderful NHS over here. I certainly wouldn't be here without it!
Good luck with all your travels and treatments.
Dave.
