I've lost 35 lbs, had to change eye glasses, always thirsty and my feet seem cold most the time. all in about six months

I'd : I'd strongly recommend you go to a doctor to get checked out. Weight loss and vision changes makes it hard not to think about blood sugar issues, like diabetes. Another thing to think about is thyroid dysfunction. All of these can be managed by your local primary care doctor, and getting what's going on under control will certainly make you feel much better.

See you doctor: These symptoms may be due to increased blood sugar levels. See your doctor to rule out diabetes.
