Grave's Disease

After surviving a heart attack in 2003 I began physical training with a heart rate monitor. The monitor gave me information on how many times my heart was beating a minute and during exercise while jogging or biking my heart rate would stay between 140 to 160 beats per minute.
In 2006 I started losing weight, down to 145 pounds from my initial 165, then I noticed I had the shakes in my thighs and hands, I thought I was getting Parkinson's Disease. A couple of other noticable changes were my ability to eat a lot and still lose weight, I was also having trouble sleeping.
My heart rate monitor started going up to 180 beats per minute while performing the same exercises in the past.
On my annual visit to my Cardologist after many visits to my family doctor, blood tests revealed I had a hyper thyroid...Grave's Disease. I started taking pills to supress my thyroid and after a year I got off the pills knowing they can have an adverse affect on our liver. My problems were in remission until a few months after the stroke in 2008 when I started feeling those familiar feelings again, so back on the thyroid supressing drug. Until earlier this month, I had Radioiodine 131 treatment. Radiation is ingested and soaked up by the thyroid and over time will kill the thyroid making me hypo thyroid and I will have to take a pill to supplement my thyroid...this pill is a more nature substance and does not have side effects like the supressant.
