true..don't panic yet...but I am 46 and I started getting those same symptoms as well a few years ago around your age..blurry vision sometimes....tired and lethargic...the tingling as well......then I started to wake up and piss three times a night and I knew something was wrong....
and sure enough I had high glucose readings in my blood...diabetes was beginning to come on....glucose levels were over 200 when it should have been 90 to 125 or so.....doctor wanted to put me on meds but I refused because I didn't want to be psychologically and physically dependent on drugs.....
I don;t like dieting because i believe they don't work and I don't like depriving myself .....all I did was keep lifting regularly and added regular cardio..plus I stopped drinking all forms of sweetened drinks..no more sodas....and no candies....that in itself was enough to bring my levels down to the 120's..I was happy and so was my doctor..doctors love it when you follow their advice and it works...

you being hispanic definitely puts you at a higher risk.....it's genetic and also the diet of hispanics is filled with starch....the bananas, Yuca, plantains, and rice and beans...my wife is hispanic so I know....good luck to you..hope this helps
