Like "August is 5 mos away...I wouldn't wait that long..when I started taking metformin my vision got really bad really fast..I went in for a full eye checkup and was told my eyes were perfectly healthy and my vision would return to normal a few weeks after my BG was kept consistently under 200....and my vision did return to normal...BUT my eye doctor told me as a diabetic I have to take any changes in my vision very seriously and if I noticed any significant changes I should see him right away...."
