insulin resistance syndrome
"Metformin they say makes you hyper-fertile.  Yea, I agree.  My hormones got a little wacky for a week or so.  I've calmed down now and feel pretty good.  I take the dose up slow, only one 500mg pill for seven days before adding one more 500 mg for another seven and so forth until I reach four pills a day.  I noticed that without using any lantus that my blood sugar readings were lower.  Not low enough however to discontinue the lantus.  I noticed while on lantus alone I never felt all that chipper.  When I started the metformin my moods improved dramatically and I became a much happier person.  The diarrhea did not last long, but did return when I increased the dose.  Getting used to the pils nowl and bowels returned to normal."
