af well bloody done! I think headaches usually mean you need more water, and maybe also to replace some of the salt you sweated out. Whole milk with ice and a good pinch of salt is disgusting, except after a long run when suddenly it was absolutely bliss when I was training - maybe try upping your water and having a small amount of extra salt after a workout (no need to go mad; couple of olives maybe if you’re into them?) Anyway, well done for getting back to it with the hard stuff - now you’ve seen an improvement you’ll start getting hooked 
lego and pixie I used to share the horror of seaweed and then one day I just suddenly didn’t give a toss anymore. It was when I was working near the sea and swimming (nervously!) every day, so maybe the secret is to keep getting in the water and each time you don’t get eaten by a monster/dragged to a watery grave by a weedy-haired sea-witch, you’ll gain a tiny bit more confidence and eventually you’ll stop fretting? Still not a fan of jellyfish though (don’t wear a wetsuit so I feel that’s a logical fear), and I’m also careful about being informed re tides and currents. The sea itself is scary and worthy of respect; seaweed just makes the water a bit warmer.
elspeth quinoa is also good where you’d normally use couscous, so with tagine or in salads.
agatha amen to fitting in more movement. If you worry too much about ‘maybe it won’t help’ you never do anything, and that definitely doesn’t give you a strong body or a balanced brain - whereas doing even a bit more than normal will build up over time to make real positive changes.
No swim today but loads of walking, and am slightly inspired to try and swim a bit more at home after seeing my arms in the mirror today and thinking “dear lord, that right there is actual muscle!” (my arms normally look like bits of spaghetti, so this is very exciting indeed). Heading home tomorrow so will try and get one last dose of Atlantic Ocean before we leave the coast. Will miss it so much - washes all the cobwebs away and makes my mind feel fresh.
