Day 10 - Energy question

I'm currently on day 10 of my 30 day water fast. I've managed to surpass my last fast (8 days) and have begun to see the difference already.

My only concern is energy is starting to become less and less common and taking water from a jug in the fridge is extremely exhausting I have to sit down and rest a bit on a chair. I tell myself I have to start moving slower because of the loss of energy and when I do things aren't as strenuous. Is this a normal feeling when on a fast? What can I do to sustain enough energy until day 30? Tweet
