to anyone else? The first day that I took 50 mcg of T3 I was feeling so strange that I couldn't go out all day. I called the FFC and they told me to stop taking it and then they re-started me on T3/4. That also made me feel a little strange but not as bad as the T3. The T3/4 did stop me from feeling so cold, but my heart is still poudning from the T3 and now I've stopped the T3/4. Last night I woke up very startled, thought I was going to die. My heart was pounding 104 times a minute for several hours. An thoughts on this? I'm afraid to go to sleep tonight!
