Water Fasting - Dont know what is happening

Good day everyone, hope all is well

Ill try and keep my question simple and straightforward:

From a few months ago When I do a water/liquid fast where I consume no solids, on day 2 I would start to experience the following symptoms:

-It starts with a tingling sensation usually at first in my hands, and would then spread through my body.

-My breathing would then start to become manual and a bit worked.

-The tingling would then go to my lips where it feels dried up as if I have eaten salt and vinegar chips. My speech would feel odd cause my lips are pulling together.

-My body temperature starts to rise and I begin to sweat, even if it is cold

-General weakness and if I recall confusion

I honestly have no idea why this is happening nor what it is as it has only started this year (the year in which I have lived a lot more healthier). I have searched but I have not found a confirmed answer yet. Every single time when I get on day 2 of fasting this happens.

Does anybody have something similar and/or know why and what this is? It is honestly extremely annoying as Im trying to do 3 day fasts again
