Hi Derek
Sorry to hear you are having a rough time, especially as you are normally one of the most positive people on here. I can't help you out I'm afraid, as I had surgery, albeit only four weeks ago. I'm just commenting to send my commiserations and keep you at the top of the leaderboard.
Enjoy your cruise mate, and don't worry about the oversize trousers, as they'll soon be redundant. I've just had to replace mine as they were falling down. I appear to be losing weight quite rapidly at the minute, which, after the novelty value wears off, is not much fun either.
Can you chat to any of the guys from your Maggies group before you head off?
Ian.
