kt, i've had recurrent hypoglycemic epidsodes throughout my life. a nutritionist i saw last year gave me some info that says some researchers believe that diabetes is a continuum from normal-hypog-ir-diabetes...and everything beyond normal is an abnormal (

) response of varying degrees. i'll try to dig it up.
in the meantime, analyze your diet. a couple docs i visited insisted that i just needed to drink more gatorade during workouts, etc. what a load! i finally saw a couple nutritionists who helped me settle things...what i finally settled on was a low sugar/ moderate carb diet with regular exercise (sounds like you have that done). a few other things that helped was eating frequent meals (i don't usually go beyond the two hour mark) and making sure they all contain protein, fat, and fiber.
as for ttc, i've heard the right off the pill thing...that didn't work for me. i took the long and slow approach where i combined charting, vitex, dong quai, diet, and exercise.
good luck!
