I am not so sure. As I said in the post I drink a lot of water.

So I wake up and have a cup of tea and for evening meal I have a can of Pepsi. Everything else in the day is just water and never less than 1.5 litres.

For me at least I think it was the climbing chalk and poor eating habits so lacking vitamins. I guess I’ll never truly know and it’s good advice to be hydrated.
