Hello millymillymilly,

I hope you're feeling better now. I think you drink too much. It's important to drink but if you drink too much you can lose alot of electrolites from your body so don't exaggerate with it.

Are you living in a hot place? what's the temp there?

Can you tell more about you? I mean for what purpose you're fasting? what's your age? gender? weight an height?

It's normal to feel swings with your energy while fasting therefore when you feel you don't have the energy get a rest for as much as your body needs( I know it can be very boring but for me it always interesting how my body react and "reset" while it fasts).Most important, listen to your body and treat him well so you can pass this much more smoothly.
