Originally, i was diagnosed with hyperthyroidism. This was about 6 years ago. I was on a beta-blocker for 3 years. Afterwards i was diagnosed as being hypothyroid (about 2.5 years ago). I've been taking synthroid ever since. At first my dosage was .075 mg. It was changed to .05 mg a year ago. I haven't gained any weight since i became hypothyroid, but i've had many other problems. Some of them include, difficulty swallowing and breathing, heaviness in throat area, memory loss, insomnia, lack of focus. These are the most serious problems.
