Brian,
I guess it was this....
Synthroid Oral Side Effects
Symptoms of low thyroid levels include fatigue, muscle aches, constipation, dry skin, weight gain, slow heart rate, sensitivity to cold, or dry brittle hair that tends to fall out easily. These symptoms should disappear as your body adjusts to the medication. If they persist or become bothersome, notify your doctor promptly.

Headache, nervousness, trembling, sweating, increased appetite, diarrhea, weight loss or insomnia may occur. If any of these effects persist or worsen, notify your doctor promptly.

In rare instances, some hair loss may occur during the first few months of starting this drug. This effect is usually temporary as your body adjusts to this medication. If this effect persists or worsens, notify your doctor promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Seek immediate medical attention if you have any of these very unlikely but serious side effects: chest pain, rapid or irregular heartbeat, shortness of breath, seizures.

An allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of an allergic reaction include: rash, itching, swelling, dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

AND..that it would probably be a life time drug. I don't think I know anyone that is on it so I didn't know if any of the side affects were "real" or just cautionary.
I did know that if I asked here I'd get the straight 'poop' from folks in the know.
Thank you one and all.....I think I'll take her up on the script and give it a try.
