Obviously I get can a blood test and AC1 test, which I plan to do, but do any members with diabetes know what symptoms can pinpoint it?

Basically I started having diabetic symptoms after using an ECA stack a few weeks ago. I urinate 3 times a night, and am always dehydrated in the morning, and drink a ton of water during the day. When eating I have periods where I have a lot of energy and also fatigue. I have always had eye floaters and see flashes in the sky, but eyes seem more sensitive lately to floaters and flashes.
