I'm on metformin for diabetes.. I was taking 200 mg twice daily my script ran out I got the flu so I went to the er and he wrote me a new script ... now I thought he upped it to 1000 mg twice daily but I got my meds and the bottles read take 2 1000 mg tabs 2 times daily .. I feel horrible .. I'm dizzy headaches ect .. my wife tells me I'm being a baby that it's just the meds doing their job .. I don't feel right ..
