Okay, so this isn’t actually about hydration, it’s about the fact that SSRIs commonly cause dry mouth as a side effect due to anticholinergic effects which reduce saliva release Some SSRIs are worse than others, and older TCAs are worse still. But OP is not dehydrated.
Water is great for hydration, but it is unfortunately not very effective at managing dry mouth due to these side effects. Flavoured beverages typically work better because they promote saliva release.
I would suggest OP add something with a sour note to their water, like lemon or lime juice which are unsweetened and have effectively no caloric component. Alternatively even just a splash of carbonated water will also work as the bubbles are irritants and will similarly stimulate saliva release.
If the yellow jersey calls for one, pee stops for the peleton are mandatory.
If a train breaks up the peleton at a level crossing, and you’re on the far side, you wait.
The final stage should have no impact on the overall classification. But this year it will as it’s a TT in Nice, not a stroll down the Champs, so it will!
If the yellow jersey falls or has a mechanical, the group they’re in, waits. (Mostly true for any competitor with a chance to win in that group)
In a breakaway, if you’re competing for points in one classification, you don’t contest points in the others if other members of the group are trying for those. So if you’re rocking the polkadot, you take it easy at the sprints.
