Like "Avandia was making me swell....metformin was causing me to black out, and I was taking Prandin which was my last and it just wasn't even lowering my bloodsugar and doing the same thing metformin did.....my doc put me on inuslin in January of 2011 with just lantus...now its novalog and lantus with an A1C of 6.8...and I feel much better...no dizzy spells or stomach pain etc etc"
