Hey folks,
I come to all of you wise people with a question - I hope you'll be able to offer some opinions and advice.
My name is Sherry, I’m 37, overweight, and hypothyroid (being treated with 75 ug Synthroid for roughly 2 years). On Thursday evening, while watching TV, I noticed that my heart rate was higher than normal - quite odd especially since I was at rest. The next day, I began feeling very strange. My heart was still racing and I felt really weird on the inside - almost like I was jittery or shaky. Perhaps it is weakness - I can’t really describe the feeling. All I know is that I just don’t feel well and haven’t since Thursday. I have taken up camp on my sofa with my TV and trusty notebook because I can't sleep. About an hour or two after falling asleep, I wake up with my heart racing and it just freaks the heck outta me!
I saw my doctor today and his initial thought was panic disorder. Say what?

I then mentioned that I recently started a weight loss and exercise program. I lost 12 lbs in 8 weeks and then began working out at the gym four times a week. He still says panic disorder.
Here is my question: Could this small weight loss/change in diet/increase in activity cause me to now be over-medicated? Could my previously adequate dose now be too much for a somewhat "smaller" me?
In any case, I pushed for blood work (which I did this morning - results wont be back till Friday). To play it safe, my doctor also sent me for an EKG, which I also did this morning. I guess those results were okay because I was told he’d have those results today and I didn’t get a phone call.
