I found out I have diabetes on May 25 2019. from the begining I had face and neck heavy sweating. I had to keep a cold cloth with me at all times. I drink so much water everyday.and eat a ton of ice.which I think helps. I am on Levemir ( insulin ) the epi pen. and after I got use to it. it did get much better. but I cannot leave the house without a class of ice water. hope things get better for you
