Overactive thyroid nodule

Hi there,

I'm a 30 yr old female recently diagnosed with an overactive thyroid nodule.  The diagnosis seems pretty conclusive, TSH <0.04, both free T3 and free T4 elevated above normal, and an uptake scan showing an overactive nodule.  My question is what course of treatment is best?  My doctor recommends RAI, but my symptoms have been mild and I'm reluctant to knowingly disable a functioning part of my endocrine system.  I have had one bout of palpitations and anxiety recently that lasted a couple of weeks, but then went away.  Other than that my only symptom has been night sweats a couple of times a month.  An added complication is that I would like to try getting pregnant in the next year or so.  I know that hyperthyroidism can have negative implications for pregnancy, and for that reason I would consider RAI.  I know also that drug therapy is an option, but I've heard that it is not a good solution for overactive nodules.

Any help or advice is greatly appreciated.

Thanks!
