Levoxyl and medical help

I love this site. I have been on Levoxyl for five years and it seems to be like a two edged sword. I had enlarged thyroid that now is practically gone, so are my heart flutterings which is a good thing....however, they have been replaced by joint pain, depression, huge appitite, and anxiety. I tried to switch to Synthriod but for me it had a Jeckle and Hyde effect and I was filled with a rage that would sweep over me. In fighting the rage I started having stomache cramps that seemed to be ulcer-like and I could find no food that didn't have me on the couch praying to God to just go ahead and take me..Switched back to Levoxyl simply because I had to have some quality of life and needed medical help...I have tried the health food route and my goiter returned. I appreciate everyone's stories because for the first time in years I see I am not alone,but I agree with those who say to keep trying and take responcibility for your own care, some doctors really do care and have every intent on our wellfare, however it has been my experience that most GP's lack the information on the diease to understand that this type of medication can do harm so they "ho, hum," us while they just keep writing out our prescriptions.
