Happy birthday Ruby'sDad! Coffee out and cake sounds perfect.
You can ask your oncy team for the drops if they don't have them in Boots - but you can get various types over the counter (mine are called Hypromellose, but there are several types, - had some from the oncy when I was having chemo with a different name, and now I have them because of thyroid eye probs)
EMIN - I had awful morning (misnomer - 'all day') sickness when pregnant, but not to bad on chemo - big waves of nausea yes - and pills to control it, but not the extreme sickness that some people get on chemo. So not a complete correlation, you may be OK 
I second ginger or peppermint or lemon herbal teas, or sipping fizzy drink like lucozade or lemonade.
What is the thing about sherry MAS - is it supposed to be good for you? - I could start having a small sherry before my meal, I quite like it.
jane - hope your mum is OK, enjoy your cake making
topsy - stop boasting, we have horrid weather here again, the nice weather of the bank holiday has obviously all headed west! Al fresco lunch with HND sounds good.
I see on the news they have stopped spraying the Mary Rose in Portsmouth, so you can see it much more clearly. I loved seeing that - very atmospheric, and so huge! -
IMO more interesting than the Victory. -(also huge but with enforced commentary from a guide and you can't turn round and go back if you don't like something - such as a horrible sort of glass path thing you can see right down to the bottom of the ship from, and have to walk across. Anyone who hated that sort of thing and was scared of heights might make a fool of themselves by trying to get down on their knees and crawl across and keep shouting 'this is awful. absolutely awful' and embarrass their daughter.) Just warning you in case you know anyone like that - so you can tell them
