Leeis,

All symptoms you described are part of fasting with water only. Everyone and every fast is different.

Eyes get rid of lot of congested mucus during a fast or even when you eat good nutrition densed foods. To clear this up quickly you can wash it with warm water with baking soda, one cup of water plus 1/2 tsp baking soda, completely dissolved. You either splash water in your eyes or wet a clean cloth with this water mix and press on the eyes.

Is your blood Sugar high? Diabetics also experience sticky eyelids, especially upon waking.

No supplements should be taken while fasting, your digestive system becomes active and benefits of Water Fast are lessend. Ketones need not be checked unless you are really curious about when you actually go in ketosis.

It would be good to know what are you trying to accomplish with your fast.

Eat plant based diet if your not already doing so. It helps with fasting.

You shouldn't take any supps or drugs during water fast, as a rule. Further you will probably not absorb them well, as fasting is a cleansing mode not a building mode, even if there wasn't the negative side of starvation which exists anytime you habituate into low-nutrition food (or fast) and give your body only certain molecules. Furthermore iron tablets can be very irritating and straight out caustic to the GIT if taken with no food.
Eye glands also can be overwhelmed with mucus, therefor the cleansing you experienced as sticky eyelids is very beneficial, as Archus pointed out.
Good job.
I also did 36 hrs dry fast and it was amazing in terms of cleansing power! I will be aiming for 48 hrs now.
