any others with thyroid problems?...

Hi, My name is Mario and I signed up just 2 weeks ago... let me tell you about my story: I'm 27 years old, 5.9 and 197 pounds... when I was 20 I was diagnosticaded with Hyperthyroidism that make me lose weight as crazy... I was around 135 pounds for around a year and feeling weak and dizzy all the time, so my doctor gave me radioactive iodine for "kill" my thyroid, after that I no longer have hyperthyroidism but as now i dont produce thyroid hormones i have Hypothyroidism, and that made gain weigh as crazy... at first i gain 30 pounds so i was actually in my normal range (165), but after a couple of years of horrible diet i when up all to 220... and for me is really hard to lose weigh as a normal person should be.. 3 years ago. I hited a plateau after the 197 mark and couldn't go down... even now i'm on medication taking my right doses, It's really frustrating so will like to know if there's any other person there with the same problem and if he or she found the way to get over it... I will try to keep you posted about my progress... thank you.
