Ok, this is just a crazy ride! Was just told last week that the Dr believes I am a diabetic, not sure if I have type 1 or type 2, awaiting results of more testing The Dr put me on 500 mg of metformin once a day. Which almost immediately halted the blurry vision i was experiencing. That was last Thursday. Today I was going to walk and before I could finish my 2 miles my heart was racing a bit and I felt shaky? I am 37,female, active, 5ft 4 and 119lbs, Do you think I could be having a drop in BS????? Just trying to figure all of this out.
