hi im new here and read your msg ,doctors thought to begin with that l was type 2 ,l was started on metformin 500mgs 4 tablets per day ,l had to take 1 tablet for a week then 2 for a week then so forth until l was taking 4 in a day .they done it that way because my nurse said they are harsh on the stomach til your body gets used to them . l felt terrible for weeks and had most of the symptoms you have .im also on medication for high blood pressure .it does settle down it can just take time ,im now on 5 injections of insulin a day and still have to take metformin ,chin up im sure it will settle soon take care x
