For the last few days I have been having blurred vision. In the morning I have been waking up with very dry eyes. I put this down to my eyes just being tired. Apparently this is a sign of de-hydration!
After having a look at this website:
Luckily it is only mild dehydration and can be reversed with plenty of water and electrolytes.
You can buy a box of electrolytes from Master Pimu.
This is taught me a very valuable lesson. The weight loss will come automatically though dont make that one's focus. One's focus should be to nurture and be kind to your body while you do such hard work.
